Functions Documentation

function plp_conv_valid_i16

void plp_conv_valid_i16(
    const int16_t * pSrcA,
    const uint32_t srcALen,
    const int16_t * pSrcB,
    const uint32_t srcBLen,
    int32_t * pRes
)

Glue code for convolution of 16-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 16-bit integer vectors.
