2.5. Computational Alternatives

There are several alternatives for executing high-performance tasks without resorting to stratospheric clock rates. These alternatives include tuning a configurable processor, splitting the task across more than one processor, and using or implementing a hardware block to perform the task. Each of these alternatives is quite viable and each should be carefully evaluated to make the most appropriate choice given overall system requirements.

Tuning a configurable processor allows the design team to retain the programmability and flexibility of a firmware-based computing element while adding parallel, programmable execution units to the processor to boost performance without raising clock rate. The industry is starting ...
