It also contains wrapper functions -to encode/decode simple length-delimited strings. This library aims to be: - -- FAST; -- easy to use; -- elegant. - -On x86, the library does runtime feature detection. The first time it's called, -the library will determine the appropriate encoding/decoding routines for the -machine. It then remembers them for the lifetime of the program. If your -processor supports AVX2, SSSE3, SSE4.1, SSE4.2 or AVX instructions, the library -will pick an optimized codec that lets it encode/decode 12 or 24 bytes at a -time, which gives a speedup of four or more times compared to the "plain" -bytewise codec. - -AVX512 support is only for encoding at present, utilizing the AVX512 VL and VBMI -instructions. Decoding part reused AVX2 implementations. For CPUs later than -Cannonlake (manufactured in 2018) supports these instructions. - -NEON support is hardcoded to on or off at compile time, because portable -runtime feature detection is unavailable on ARM. - -Even if your processor does not support SIMD instructions, this is a very fast -library. The fallback routine can process 32 or 64 bits of input in one round, -depending on your processor's word width, which still makes it significantly -faster than naive bytewise implementations. On some 64-bit machines, the 64-bit -routines even outperform the SSSE3 ones. - -To the author's knowledge, at the time of original release, this was the only -Base64 library to offer SIMD acceleration. The author wrote -[an article](http://www.alfredklomp.com/programming/sse-base64) explaining one -possible SIMD approach to encoding/decoding Base64. The article can help figure -out what the code is doing, and why. - -Notable features: - -- Really fast on x86 and ARM systems by using SIMD vector processing; -- Can use [OpenMP](http://www.openmp.org) for even more parallel speedups; -- Really fast on other 32 or 64-bit platforms through optimized routines; -- Reads/writes blocks of streaming data; -- Does not dynamically allocate memory; -- Valid C99 that compiles with pedantic options on; -- Re-entrant and threadsafe; -- Unit tested; -- Uses Duff's Device. - -## Acknowledgements - -The original AVX2, NEON and Aarch64/NEON codecs were generously contributed by -[Inkymail](https://github.com/inkymail/base64), who, in their fork, also -implemented some additional features. Their work is slowly being backported -into this project. - -The SSSE3 and AVX2 codecs were substantially improved by using some very clever -optimizations described by Wojciech Muła in a -[series](http://0x80.pl/notesen/2016-01-12-sse-base64-encoding.html) of -[articles](http://0x80.pl/notesen/2016-01-17-sse-base64-decoding.html). -His own code is [here](https://github.com/WojciechMula/toys/tree/master/base64). - -The AVX512 encoder is based on code from Wojciech Muła's -[base64simd](https://github.com/WojciechMula/base64simd) library. - -The OpenMP implementation was added by Ferry Toth (@htot) from [Exalon Delft](http://www.exalondelft.nl). - -## Building - -The `lib` directory contains the code for the actual library. -Typing `make` in the toplevel directory will build `lib/libbase64.o` and `bin/base64`. -The first is a single, self-contained object file that you can link into your own project. -The second is a standalone test binary that works similarly to the `base64` system utility. - -The matching header file needed to use this library is in `include/libbase64.h`. - -To compile just the "plain" library without SIMD codecs, type: - -```sh -make lib/libbase64.o -``` - -Optional SIMD codecs can be included by specifying the `AVX2_CFLAGS`, `AVX512_CFLAGS`, -`NEON32_CFLAGS`, `NEON64_CFLAGS`, `SSSE3_CFLAGS`, `SSE41_CFLAGS`, `SSE42_CFLAGS` and/or `AVX_CFLAGS` environment variables. -A typical build invocation on x86 looks like this: - -```sh -AVX2_CFLAGS=-mavx2 SSSE3_CFLAGS=-mssse3 SSE41_CFLAGS=-msse4.1 SSE42_CFLAGS=-msse4.2 AVX_CFLAGS=-mavx make lib/libbase64.o -``` - -### AVX2 - -To build and include the AVX2 codec, set the `AVX2_CFLAGS` environment variable to a value that will turn on AVX2 support in your compiler, typically `-mavx2`. -Example: - -```sh -AVX2_CFLAGS=-mavx2 make -``` - -### AVX512 - -To build and include the AVX512 codec, set the `AVX512_CFLAGS` environment variable to a value that will turn on AVX512 support in your compiler, typically `-mavx512vl -mavx512vbmi`. -Example: - -```sh -AVX512_CFLAGS="-mavx512vl -mavx512vbmi" make -``` - -The codec will only be used if runtime feature detection shows that the target machine supports AVX2. - -### SSSE3 - -To build and include the SSSE3 codec, set the `SSSE3_CFLAGS` environment variable to a value that will turn on SSSE3 support in your compiler, typically `-mssse3`. -Example: - -```sh -SSSE3_CFLAGS=-mssse3 make -``` - -The codec will only be used if runtime feature detection shows that the target machine supports SSSE3. - -### NEON - -This library includes two NEON codecs: one for regular 32-bit ARM and one for the 64-bit AArch64 with NEON, which has double the amount of SIMD registers and can do full 64-byte table lookups. -These codecs encode in 48-byte chunks and decode in massive 64-byte chunks, so they had to be augmented with an uint32/64 codec to stay fast on smaller inputs! - -Use LLVM/Clang for compiling the NEON codecs. -The code generation of at least GCC 4.6 (the version shipped with Raspbian and used for testing) contains a bug when compiling `vstq4_u8()`, and the generated assembly code is of low quality. -NEON intrinsics are a known weak area of GCC. -Clang does a better job. - -NEON support can unfortunately not be portably detected at runtime from userland (the `mrc` instruction is privileged), so the default value for using the NEON codec is determined at compile-time. -But you can do your own runtime detection. -You can include the NEON codec and make it the default, then do a runtime check if the CPU has NEON support, and if not, force a downgrade to non-NEON with `BASE64_FORCE_PLAIN`. - -These are your options: - -1. Don't include NEON support; -2. build NEON support and make it the default, but build all other code without NEON flags so that you can override the default at runtime with `BASE64_FORCE_PLAIN`; -3. build everything with NEON support and make it the default; -4. build everything with NEON support, but don't make it the default (which makes no sense). - -For option 1, simply don't specify any NEON-specific compiler flags at all, like so: - -```sh -CC=clang CFLAGS="-march=armv6" make -``` - -For option 2, keep your `CFLAGS` plain, but set the `NEON32_CFLAGS` environment variable to a value that will build NEON support. -The line below, for instance, will build all the code at ARMv6 level, except for the NEON codec, which is built at ARMv7. -It will also make the NEON codec the default. -For ARMv6 platforms, override that default at runtime with the `BASE64_FORCE_PLAIN` flag. -No ARMv7/NEON code will then be touched. - -```sh -CC=clang CFLAGS="-march=armv6" NEON32_CFLAGS="-march=armv7 -mfpu=neon" make -``` - -For option 3, put everything in your `CFLAGS` and use a stub, but non-empty, `NEON32_CFLAGS`. -This example works for the Raspberry Pi 2B V1.1, which has NEON support: - -```sh -CC=clang CFLAGS="-march=armv7 -mtune=cortex-a7" NEON32_CFLAGS="-mfpu=neon" make -``` - -To build and include the NEON64 codec, use `CFLAGS` as usual to define the platform and set `NEON64_CFLAGS` to a nonempty stub. -(The AArch64 target has mandatory NEON64 support.) -Example: - -```sh -CC=clang CFLAGS="--target=aarch64-linux-gnu -march=armv8-a" NEON64_CFLAGS=" " make -``` - -### OpenMP - -To enable OpenMP on GCC you need to build with `-fopenmp`. This can be by setting the the `OPENMP` environment variable to `1`. - -Example: - -```sh -OPENMP=1 make -``` - -This will let the compiler define `_OPENMP`, which in turn will include the OpenMP optimized `lib_openmp.c` into `lib.c`. - -By default the number of parallel threads will be equal to the number of cores of the processor. -On a quad core with hyperthreading eight cores will be detected, but hyperthreading will not increase the performance. - -To get verbose information about OpenMP start the program with `OMP_DISPLAY_ENV=VERBOSE`, for instance - -```sh -OMP_DISPLAY_ENV=VERBOSE test/benchmark -``` - -To put a limit on the number of threads, start the program with `OMP_THREAD_LIMIT=n`, for instance - -```sh -OMP_THREAD_LIMIT=2 test/benchmark -``` - -An example of running a benchmark with OpenMP, SSSE3 and AVX2 enabled: - -```sh -make clean && OPENMP=1 SSSE3_CFLAGS=-mssse3 AVX2_CFLAGS=-mavx2 make && OPENMP=1 make -C test -``` - -## API reference - -Strings are represented as a pointer and a length; they are not -zero-terminated. This was a conscious design decision. In the decoding step, -relying on zero-termination would make no sense since the output could contain -legitimate zero bytes. In the encoding step, returning the length saves the -overhead of calling `strlen()` on the output. If you insist on the trailing -zero, you can easily add it yourself at the given offset. - -### Flags - -Some API calls take a `flags` argument. -That argument can be used to force the use of a specific codec, even if that codec is a no-op in the current build. -Mainly there for testing purposes, this is also useful on ARM where the only way to do runtime NEON detection is to ask the OS if it's available. -The following constants can be used: - -- `BASE64_FORCE_AVX2` -- `BASE64_FORCE_AVX512` -- `BASE64_FORCE_NEON32` -- `BASE64_FORCE_NEON64` -- `BASE64_FORCE_PLAIN` -- `BASE64_FORCE_SSSE3` -- `BASE64_FORCE_SSE41` -- `BASE64_FORCE_SSE42` -- `BASE64_FORCE_AVX` - -Set `flags` to `0` for the default behavior, which is runtime feature detection on x86, a compile-time fixed codec on ARM, and the plain codec on other platforms. - -### Encoding - -#### base64_encode - -```c -void base64_encode - ( const char *src - , size_t srclen - , char *out - , size_t *outlen - , int flags - ) ; -``` - -Wrapper function to encode a plain string of given length. -Output is written to `out` without trailing zero. -Output length in bytes is written to `outlen`. -The buffer in `out` has been allocated by the caller and is at least 4/3 the size of the input. - -#### base64_stream_encode_init - -```c -void base64_stream_encode_init - ( struct base64_state *state - , int flags - ) ; -``` - -Call this before calling `base64_stream_encode()` to init the state. - -#### base64_stream_encode - -```c -void base64_stream_encode - ( struct base64_state *state - , const char *src - , size_t srclen - , char *out - , size_t *outlen - ) ; -``` - -Encodes the block of data of given length at `src`, into the buffer at `out`. -Caller is responsible for allocating a large enough out-buffer; it must be at least 4/3 the size of the in-buffer, but take some margin. -Places the number of new bytes written into `outlen` (which is set to zero when the function starts). -Does not zero-terminate or finalize the output. - -#### base64_stream_encode_final - -```c -void base64_stream_encode_final - ( struct base64_state *state - , char *out - , size_t *outlen - ) ; -``` - -Finalizes the output begun by previous calls to `base64_stream_encode()`. -Adds the required end-of-stream markers if appropriate. -`outlen` is modified and will contain the number of new bytes written at `out` (which will quite often be zero). - -### Decoding - -#### base64_decode - -```c -int base64_decode - ( const char *src - , size_t srclen - , char *out - , size_t *outlen - , int flags - ) ; -``` - -Wrapper function to decode a plain string of given length. -Output is written to `out` without trailing zero.
