Simplifying the programming models is paramount to the success of reconfigu
rable computing with field programmable gate arrays (FPGAs). This paper pre
sents a methodology to combine true object-oriented design of the compiler/
CAD tool with an object-oriented hardware design methodology in C++. The re
sulting system provides all the benefits of object-oriented design to the c
ompiler/CAD tool designer and to the hardware designer/programmer. The two
examples for domain-specific compilers presented are BSAT and StReAm, Each
domain-specific compiler is targeted at a very specific application domain,
such as applications that accelerate Boolean satisfiability problems with
BSAT, and applications which lend themselves for implementation as a stream
architecture with StReAm. The key benefit of the presented domain specific
compilers is a reduction of design time by orders of magnitude while keepi
ng the optimal performance of hand-designed circuits.
