COARSE-GRAINED RECONFIGURABLE ARRAY BASED ON A STATIC ROUTER

摘要

PURPOSE: A static router-based CGRA(Coarse-Grained Reconfigurable Array) is provided to enhance the whole performance, and to reduce overheads caused by data delivery using a static router for data delivery between processing elements composing the CGRA. CONSTITUTION: A router(102) is connected to PEs(Processing Elements)(101) and a connection link is connected between routers. The PEs include a function unit(210) performing arithmetic or logic operations and a register file(220) storing data related to the arithmetic or logic operations. The router receives the data from a connected PE or an adjacent router and transmits the data to the connected PE or the adjacent router by designated compile information. The router includes a receiving unit receiving the data, a determining unit determining an output direction of the data according to the compile information, and an output unit.
