Gati Platform

GATI IS NOW OPEN !! 🎉 🥳

Gati is a FPGA based reconfigurable CNN inference platform developed by team by Vicharak. Reconfigurable in a way that it let's you generate the hardware only necessary for the target model.

Gati Currently supports a plethora of operators which can be arranged accordingly to support a list of models.

Hardware

Gati Platfrom is currently Supported on the Vaaman FPGA SBC Developed By Vicharak.

To generate a bitstream for your target model, follow instructions in hardware/README.md.

To use this on your Vaaman read this doc to setup your vaaman.

Supported Models

The list of pre quantized model is available in the release section of the repo . However it is not limited to these models.
