Description

The HVX Conv2D block performs a two-dimensional (2-D) convolution of an input image using a square filter mask for Hexagon^® Vector eXtension (HVX).

Ports

Input

Input — 2-D input matrix

2-D matrix

2-D input matrix whose width is a multiple of 128. The height of the matrix must be greater than or equal to the mask size.

Data Types: uint8

Mask — Structuring element

3-by-3 matrix (default) | 5-by-5 matrix | 7-by-7 matrix

Structuring element, specified as a two-dimensional square matrix of size 3, 5, or 7.

Data Types: int8

Output

Output — Convolution output

matrix

Convolution output of the input matrix and the mask, returned as a matrix.

Data Types: uint8

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"mwqhvxipcvlib/HVX Conv2D"

Example: add_block("mwqhvxipcvlib/HVX Conv2D","myModel/myBlock",MakeNameUnique="on")
