Embedded systems often must adhere to strict size, weight, and power (SWAP) constraints and yet provide tremendous computational throughput. Increasing the difficulty of this challenge, there is a trend to utilize commercial-off-the-shelf (COTS) components in the design of such systems to reduce both total cost and time to market. Employment of COTS components also promotes standardization and permits a more generalized approach to system evaluation and design than do systems designed at the applicatiospecific-integrated-circuit (ASIC) level. The computationally intensive application of synthetic aperture radar (SAR) is by nature a high-performance embedded application that lends itself to parallelization. A system performance model, in the context of SWAP, is developed based on mathematical programming. This work proposes an optimization technique using a combination of constrained nonlinear and integer programming.
