function plp_conv_valid_i8

void plp_conv_valid_i8(
    const int8_t * pSrcA,
    const uint32_t srcALen,
    const int8_t * pSrcB,
    const uint32_t srcBLen,
    int32_t * pRes
)

Glue code for convolution of 8-bit integer vectors in valid range.

Parameters:

• pSrcA points to the first input vector
• srcALen ength of the first input vector
• pSrcB points to the second input vector
• srcBLen Length of the second input vector
• pRes output result returned here, of size |srcALen - srcBLen| + 1

Return: none

Glue code for convolution (valid) of 8-bit integer vectors.
