The focus of our paper is on the architectural and compiler support for subword parallelism. We introduce an intelligent Demand Driven Register Allocation Framework (DDRAF). This scheme addresses the fundamental bottleneck of global register allocation for subword sized variables. This will lead to high performance media processors that exploit parallel behavior in a program at run-time on fine grain (subword) level. Further the future aim is to fine tune compilers for latency reduction for media applications. It has been seen that the quality of the audio/ video data depends on the ability of the processors to execute multiple subword data in parallel.
