+# [RustCrypto]: CPU Feature Detection

+
+Lightweight and efficient runtime CPU feature detection for `aarch64` and
+`x86`/`x86_64` targets.
+
+Supports `no_std` as well as mobile targets including iOS and Android,
+providing an alternative to the `std`-dependent `is_x86_feature_detected!`
+macro.
+
+[Documentation][docs-link]
+
+## Supported architectures
+
+### `aarch64`: Android, iOS, Linux, and macOS/M4 only
+
+Note: ARM64 does not support OS-independent feature detection, so support must
+be implemented on an OS-by-OS basis.
+
+Target features:
+
+- `aes`
+- `sha2`
+- `sha3`
+
+Note: please open a GitHub Issue to request support for additional features.
+
+### `x86`/`x86_64`: OS independent and `no_std`-friendly
+
+Target features:
+
+- `adx`
+- `aes`
+- `avx`
+- `avx2`
+- `bmi1`
+- `bmi2`
+- `fma`
+- `mmx`
+- `pclmulqdq`
+- `popcnt`
+- `rdrand`
+- `rdseed`
+- `sgx`
+- `sha`
+- `sse`
+- `sse2`
+- `sse3`
+- `sse4.1`
+- `sse4.2`
+- `ssse3`
