ROUTING SYSTEM, FLOW CONTROL METHOD, BUFFER MANAGEMENT SYSTEM AND BUFFER MANAGEMENT METHOD FOR REDUCING LEAKAGE POWER IN ON-CHIP NETWORK

摘要

PURPOSE: A routing system for reducing leaked power, a flow control method, a buffer management system, and a buffer management method thereof are provided to reduce leaked power by individually deactivating buffer entries including the buffer of a router on an on-chip network. CONSTITUTION: A buffer entry state management unit(1210) manages a plurality of buffer entries as an on state or an off state. A fleet data management unit(1220) stores one of the buffer entries from an upstream router. The fleet data management unit transmits the stored fleet data to a downstream router. A credit transmission unit(1230) transmits an initial credit and a normal credit to the upstream router. The initial credit is matched with the fleet data received from the upstream router. The normal credit is matched with the fleet data transmitted to the downstream router.
