Conventional register files spread porting resources uniformly across all registers. This paper proposes a method called Asymmetric Clustering using a Register Cache (ACRC). ACRC utilizes a fast register cache that concentrates valuable register file ports to the most active registers thereby reducing the total register file area and power consumption....
The amount of instruction level parallelism (ILP) that can be exploited depends
greatly on the size of the instruction window and the number of in-flight instructions
the processor can support. However, this requires a register file with a large set of
physical registers for renaming and multiple ports to provide...
The purpose of this thesis is to explore methods which can reduce the power dissipation of a mobile system while decoding MPEG video. MPEG decoding is a microprocessor intensive process that makes heavy use of both the L1 and L2 caches as well as main memory. The heavy load placed...
