The Transmogrifier-2 Field Programmable System

 

AWARD: The Transmogrifier-2 Wins CMC Texpo Award for Novel Use of Microelectronic Components in the development of novel applications.

Introduction

The Transmogrifier-2 is a next-generation field-programmable system currently under construction at the University of Toronto. The goal of this project is provide a Field-programmable system with a usable logic capacity in excess of 2 Million gates.

What is the TM-2 Doing Right Now?

Click here to see the status of the Transmogrifier-2 - who is currently using it, the name of the program, and which boards and chips of the TM-2 are programmed. Please be patient, as this is a little bit slow for some strange WWW server reasons.

The Board

The TM-2a consists of up to 16 boards, each of which contains:

Here is a picture of the older version of the board, which uses Altera 10K50 FPGAs: [The Transmogrifier-2 Board]

The System

The boards are connected by a backplane. The TM-2 has a novel inter-FPGA routing architecture (using the I-cubes crossbar chips) that gives routability in systems that scale from 2 boards up to 16 boards.

The latter system, with 16 boards contains 32 Altera 10K100 FPGAs. This provides a nominal logic capacity of 100K x 32 = 3.2M gates. More realistically, counting only the lookup tables on the devices at 12 gates/LUT-FF pair, then a 16 board system yields 1.9M gates not including 768K bits of on-chip RAM.

Papers and Documentation

These Postscript documents describe some of the details of the TM-2 and the support software:

         A paper that describes the architecture and some of the software of the TM-2: D. Lewis, D. Galloway, M. van Ierssel, J. Rose, P. Chow, "The Transmogrifier-2: A 1 Million Gate Rapid Prototyping System," in FPGA `97, ACM Symp. on FPGAs, Feb 1997, pp. 53-61.

         A longer, more recent version of the paper describing the TM-2, D. Lewis, D. Galloway, M. van Ierssel, J. Rose, P. Chow, "The Transmogrifier-2: A 1 Million Gate Rapid Prototyping System," in submission.

         An Example Application for the TM-2 is a step by step tutorial that tells you how to compile a simple example design, download it into the TM-2 and communicate with the design from a program on a UNIX workstation.

         The manual for the Transmogrifier C language and compiler, which can be used to describe circuits for the TM-2.

         The TM-2 Ports Package manual describes the library of routines that a C program can use to communicate with a design in the TM-2.

         Creating and Running Circuits for the TM-2 describes the commands available for controlling and programming the TM-2.

         The tm2mon Program describes the daemon that connects the TM-2 hardware to the network.

One of the Working Applications - Graphics Acceleration

We are currently using the TM-2 to develop graphics acceleration algorithms. The first project was to draw polygons. The second is to use a procedural texture mapping techniques to fill the polygons. Below we have two examples of a set of triangles that have been procedurally texture mapped, with some simple textures. Note that in actual operation, these triangles are bouncing around the screen.

A second example:

The People

The architecture of the board was developed by David Lewis , David Galloway, Marcus van Ierssel, Jonathan Rose , and Paul Chow , with some specification input from Michael Ayukawa, formerly of Nortel , now with Chip Express . The board was built by Marcus van Ierssel, and debugged with the aid of David Galloway. David Galloway wrote the software to do the above graphics acceleration.
