Chapter 8. Challenges to Automatic Customization
Nigel Topham
Architectural customization is a powerful technique for improving the performance and energy efficiency of embedded processors. In principle, by identifying application-specific hardware functionality, it is possible to obtain a close fit between what hardware provides and the computations performed by the target application [1]. In contrast, a general-purpose processor (GPP) will typically execute a sequence of generic instructions to implement the same functionality found in a single application-specific instruction. An obvious benefit of application-specific instructions is to simply reduce the number and overall size of executed instructions, allowing the same real-time performance ...
