In spite of the multicore revolution, high single thread performance still plays an important role in ensuring a decentoverall gain. Look-ahead is a proven strategy in uncoveringimplicit parallelism; however, a conventional out-of-ordercore quickly becomes resource-inefficient when looking beyond a short distance. An effective approach is to use an in-dependent look-ahead thread running on a separate...
Despite the proliferation of multi-core and multi-threaded architectures, exploiting implicit parallelism for a single semantic thread is still a crucial component in achieving high performance. Lookahead is a "tried-and-true" strategy in uncovering implicit parallelism. However, a conventional, monolithic out-of-order core quickly becomes resource-inefficient when looking beyond a small...

While a canonical out-of-order engine can effectively exploit implicit parallelism in sequential programs, its effectiveness is often hindered by instruction and data supply imperfections manifested as branch mispredictions and cache misses. Accurate and deep look-ahead guided by a slice of the executed program is a simple yet effective approach to mitigate the performance impact of branch mispredictions...
In this paper, we present the design theory and fabrication process integration of 65 nm and 32 nm node Si and Si1-xGex vertical dual carrier field effect transistor (VDCFET) CPU for arrays of parallel computers. The design theory includes the design of complementary VDCFET devices and their high speed circuits. The fabrication process includes molecular beam epitaxy, electron beam lithography, selective...
