Apr 2016: Taped out BRGTC1, our
first computer
architecture test chip: a 2x2mm 1.3M-transistor chip in IBM 130nm
designed and implemented using our new PyMTL hardware modeling
framework. The chip includes a simple pipelined 32-bit RISC
processor, custom LVDS clock receiver, 16KB of on-chip SRAM, and
application-specific accelerators generated using commercial C-to-RTL
high-level synthesis tools. Project was led by Christopher Torng and
Moyang Wang with contributions from Bharath Sudheendra & Nagaraj
Murali (physical design), Suren Jayasuriya & Robin Ying
(full-custom design), Shreesha Srinath (accelerator design), and
Taylor Pritchard (FPGA emulation).
