Abstract :
Godson-T is a research many-core processor designed for parallel scientific computing that delivers efficient performance and flexible programmability simultaneously. It also has many features to achieve high efficiency for on-chip resource utilization, such as a region-based cache coherence protocol, data transfer agents, and hardware-supported synchronization mechanisms. Finally, it also features a highly efficient runtime system, a Pthreads-like programming model, and versatile parallel libraries, which make this many-core design flexibly programmable.
