His more recent work has focused on novel architectures for embedded systems. Building on the KSU CS Department's historical strength in parallel computing, he and many of his students have explored the use of associative SIMD computing techniques on FPGAs, demonstrating their suitability for embedded systems running such applications as data mining, image processing, etc. With another student (now an alumnus), he is exploring techniques for improving instruction cache performance in embedded systems.
