void	plp_copy_f32s_rv32im(float32_t restrict pSrc, float32_t restrict pDst, uint32_t blockSize) Copies the elements of a 32-bit integer vector for XPULPV2 extension.
void	plp_copy_f32s_xpulpv2(float32_t restrict pSrc, float32_t restrict pDst, uint32_t blockSize) Copies the elements of a 32-bit integer vector for XPULPV2 extension.
void	plp_copy_i32s_rv32im(int32_t restrict pSrc, int32_t restrict pDst, uint32_t blockSize) Copies the elements of a 32-bit integer vector for RV32IM extension.
void	plp_copy_i32s_xpulpv2(int32_t restrict pSrc, int32_t restrict pDst, uint32_t blockSize) Copies the elements of a 32-bit integer vector for XPULPV2 extension.

Detailed Description

Copies sample by sample from source vector to destination vector. pDst[n] = pSrc[n]; 0 <= n < blockSize. There are separate functions for floating point, integer, and fixed point 32- 16- 8-bit data types. For lower precision integers (16- and 8-bit), functions exploiting SIMD instructions are provided.

The naming scheme of the functions follows the following pattern (for example plp_dot_prod_i32s): _ _ _ , with

data type = {f, i, q} respectively for floats, integers, fixed points

precision = {32, 16, 8} bits

method = {s, p} respectively meaning single core or parallel multicore implementation.

isa extension = rv32im, xpulpv2, etc. of which rv32im is the most general one.
