Abstract

Modern FPGAs contain abundant resources that suggest a potential for being first class computation devices. However, they are rarely used for computation due to the difficulty involved in using them. I will present a system that compiles perfect loop nests, common in scientific computing applications, to optimized FPGA implementations. I’ll discuss how we create parallel designs from sequential code, optimize memory accesses to reduce DRAM bandwidth requirements, and produce compiled designs for either Altera or Xilinx boards.
