Cross-platform FPGA accelerator development using CoRAM and CONNECT

Abstract

The CoRAM memory architecture is an easy-to-use and portable abstraction for FPGA accelerator development [1, 2]. Using the CoRAM framework, FPGA developers can write their applications once and re-target them automatically to different FPGA platforms and devices (e.g., Xilinx ML605, Altera DE4, ZYNQ-702, etc). In this tutorial, participants will learn the key concepts of the CoRAM Virtual Architecture and the underlying CONNECT Network-on-Chip generation framework [3]. The tutorial is organized into three parts. The first part will provide an overview of the CoRAM Virtual Architecture and include a hands-on section where participants will work on a small example to get first-hand experience with the CoRAM development flow. The second part of the tutorial will provide a beneath-the-hood look at CoRAM and cover more advanced topics. These topics include memory loading, user I/O, debugging, as well as a segment on the CONNECT NoC generation framework which serves as the on-chip interconnect for CoRAM. The final part of the tutorial will be devoted to more advanced exercises and demos, as well as a Q&A session for CoRAM and CONNECT. The tutorial assumes a basic understanding of RTL design and C programming. To join in on the hands-on exercise, the attendees need laptops with 15GB of free space and VirtualBox installed.
