RVV defines a total of 12 different extensions, including: - 5 different instruction subsets: - Zve32x: 8-, 16- and 32-bit integers, - Zve32f: Zve32x plus single precision floats, - Zve64x: Zve32x plus 64-bit integers, - Zve64f: Zve32f plus Zve64x, - Zve64d: Zve64f plus double precision floats. - 6 different vector lengths: - Zvl32b (embedded only), - Zvl64b (embedded only), - Zvl128b, - Zvl256b, - Zvl512b, - Zvl1024b, - and the V extension proper: equivalent to Zve64f and Zvl128b. In total, there are 6 different possible sets of supported instructions (including the empty set), but for convenience we allocate one bit for each type sets: up-to-32-bit ints (RVV_I32), floats (RVV_F32), 64-bit ints (RVV_I64) and doubles (RVV_F64). Whence the vector size is needed, it can be retrieved by reading the unprivileged read-only vlenb CSR. This should probably be a separate helper macro if needed at a later point. |
