In this talk, I will describe a new high-level synthesis tool, called LegUp, being developed at the University of Toronto. LegUp accepts a standard C program as input and automatically compiles the program to a hybrid architecture containing an FPGA -based MIPS soft processor and custom hardware accelerators that communicate through a standard bus interface. In the hybrid processor/accelerator architecture, program segments that are unsuitable for hardware implementation can execute in software on the processor. Results show that the tool produces hardware solutions of comparable quality to a commercial high-level synthesis tool. We also give results demonstrating the ability of the tool to explore the hardware/software co-design space by varying the amount of a program that runs in software vs. hardware. LegUp, along with a set of benchmark C programs, is open source and freely downloadable (www.legup.org), providing a powerful platform that can be leveraged for new research on a wide range of high-level synthesis topics. The talk will overview LegUp’s current capabilities, as well as research underway.
