A Soft Dual-Processor System with a Partially Run-Time Reconfigurable Shared 128-Bit SIMD Engine

In this work, we present a soft dual-processor system that, as a distinctive feature, seamlessly integrates a partially run-time reconfigurable 128-bit SIMD engine. Importantly, the SIMD engine is tightly coupled to both scalar CPUs and it is shared amongst them with the purpose of drastically improving overall area utilization. We show that the proposed SIMD engine increases performance-per-area and that it can be used to substantially accelerate time consuming kernels for a set of media applications.
