Abstract

Abstract: Systems composed of microprocessors interacting with ASICs are necessarily multiple-process systems, since the controller in the microprocessor is separate from any controllers on the ASIC. For this reason, the design of such systems offers an opportunity to exploit not only hardware-software tradeoffs, but concurrency tradeoffs as well. The paper describes an automated iterative improvement technique for performing concurrency optimization and hardware-software tradeoffs simultaneously. Experimental results illustrate that addressing these two issues simultaneously enables us to identify a number of interesting cost/performance points that would not have been found otherwise.
