【 摘 要 】

This dissertation extends a WELD for Itanium processors. Emre Özer presented WELD architecture in his Ph.D. thesis. WELD integrates multithreading support into an Itanium processor to hide run-time latency effects that cannot be determined by the compiler. Also, it proposes a hardware technique called operation welding that merges operations from different threads to utilize the hardware resources. Hardware contexts such as program counters and the fetch units are duplicated to support for multithreading. The experimental results show that Dual-thread WELD attains a maximum of 11% speedup as compared to single-threaded Itanium architecture while still maintaining the hardware simplicity of the EPIC architecture.
