function plp_offset_i8s_xpulpv2

void plp_offset_i8s_xpulpv2(
    const int8_t * pSrc,
    int8_t offset,
    int8_t * pDst,
    uint32_t blockSize
)

add a constant offset to a vector for 8-bit integers on XpulpV2

Parameters:

• pSrc points to the input vector
• offset is the offset to be added
• pDst points to the output vector
• blockSize number of samples in each vector

Return: none
