Abstract
This demo elaborates on the programmability aspect of Simodense, a recently released open-source softcore, optimised for evaluating custom SIMD instructions. CPUs featuring small reconfigurable areas for implementing custom instructions is an alternative path in computer architecture that can help with the challenges found in today’s FPGAs. By providing RTL-based programmability for implementing custom SIMD instructions, highly-integrated accelerators can be developed, while benefiting from the pre-existing CPU logic, such as the caches and their high memory throughput to main memory.
