Performance of applications can be boosted by executing application-specific Instruction Set Extensions (ISEs) on a specialized hardware coupled with a processor core. Many commercially available customizable processors have communication overheads in their interface with the specialized hardware. However, existing ISE generation approaches have not considered customizable processors that have communication overheads at their interface. Furthermore, they have not characterized the energy benefits of such ISEs. This paper presents a soft-processor customization framework that takes an input 'C' application and realizes a customized processor capturing the microarchitectural details of its interface with the specialized unit.
