553 : 3x3 Clock Rate Streaming Input Convolution Engine
- Author: Yahya Numan Incirkus
- Description: 3x3 linear convolution through a singular MAC unit, 8-bit pixel input 6-bit weights
- GitHub repository
- Open in 3D viewer
- Open in Tiny Tapeout Explorer
- Clock: 500000 Hz
How it works
Standard MAC operation for linear convolution
How to test
Feed 9 Pixels sequentially, 8 bits each with tuser pin ran high when 1st of each 9 pixel array is fed. wghupdates switches the pixel feed line into weight feed and rndgset sets the shifting amount to accomodate different filter structures.
External hardware
