Abstract:
CHiMPS (Compiling High level language to
Massively Pipelined System) system, developed by
Xilinx is gaining popularity due to its convenient
computational model and architecture for field
programmable gate array computing. The CHiMPS
system utilizes CHiMPS target language as an
intermediate representation to bridge between the high
level language and the data flow architecture
generated from it. However, currently the CHiMPS
frontend does not provide many commonly used
optimizations and has some use restrictions. In this
paper we present an alternative compiler environment
based on low level virtual machine compiler
environment extended to generate CHiMPS target
language code for the CHiMPS architecture. Our
implementation provides good support for global
optimizations and analysis and overcomes many
limitations of the original Xilinx CHiMPS compiler.
Simulation results from codes based on this approach
show to outperform those obtained with the original
CHiMPS compiler.
