High bandwidth of networks demands high performance communication processors that integrate application processing, network processing, and system support functions into a single, low cost System-On-Chip (SOC) solution. However, conventional processors, when used in network related applications, are beset by the overhead of save/restore of register context, cache misses due to...
General purpose computer systems have seen increased performance potential through the parallel processing capabilities of multicore processors. Yet this potential performance can only be attained through parallel applications, thus forcing software developers to rethink how everyday applications are designed. The most readily form of Thread Level Parallelism (TLP) within any...
Dynamic multithreaded processors attempt to increase the performance of a single
sequential program by dynamically extracting threads from sources such as loop
iterations. The scheduling of instructions in such a processor plays a vital role in the
amount of thread level parallelism that can be extracted and thus the overall...
The purpose of this thesis is to explore dependency speculation in Dynamic Simultaneous Multi-Threading (DSMT). DSMT is a microprocessor architecture which attempts to extract Thread Level Parallelism (TLP) from single-threaded programs at run-time. This is accomplished by running multiple iterations of program loops in parallel. The DSMT architecture was originally...
