The LEAP multiFPGA compiler operates on programs consisting of latency-insensitive modules.

This model of computation are similar to Kahn Process Networks . However, latency-insensitive channels do not have blocking reads.

LIM compilation has a strong correspondence to the compilation of soft connections for a single FPGA. Indeed, LIM compilation targeting a single FPGA is functionally equivalent to the basic LEAP soft_connections compilation flow.

The multiple FPGA compiler accepts all LEAP connected_applications describe in terms of AWB .apm files. In addition to the .apm describing the program, two additional input files are required:

• Environment File describing the set of FPGAs to which the program will be mapped

• Mapping File describes how the program will be mapped onto the environment. Eventually this will be automated.
