 Benchmark   | Description
 ----------- | -----------
 Proto       | Instruction-focused.
 Swissmap    | Data-focused.
-Libc        | Data-focused.
+Libc        | Data-focused. Benchmarking `memcpy`, `memcmp/bcmp`, `memset`, and `memmove`.
 TCMalloc    | Data-focused.
 Compression | Data-focused. Covers [Snappy](https://github.com/google/snappy), [ZSTD](https://facebook.github.io/zstd/), [Brotli](https://github.com/google/brotli), and Zlib.
 Hashing     | Data-focused. Supports algorithms [CRC32](https://github.com/abseil/abseil-cpp/tree/master/absl/crc) and [absl::Hash](https://github.com/abseil/abseil-cpp/tree/master/absl/hash).
 STL-Cord    | Instruction-focused.
+RPC         | Instruction-focused with a strong data-drive aspect and buit on [gRPC framework](https://grpc.io)
+SIMD        | [ScaNN LUT16](https://research.google/blog/announcing-scann-efficient-vector-similarity-search/) based and measures performance of lookup-and-accumulate.
