Abstract
DMA channel receive packet comparator logic (74) of PCI-interface ASIC (20) assigns a data packet (106) through a data communications channel and includes DMA channel comparator logic (110) for receiving at least a portion of an incoming data packet (108) in data comparison circuit (110). Data packet comparison circuit (120) compares at least a portion of incoming data packet (108) to a predetermined match data set (122). Packet portion (108) and the match data set (122) form programmably varying data fields (WD0, WD1) corresponding to at least one data communications channel (117, 119,121, 123). In the event of a predetermined correspondence between portion (108) and match data set (122), a channel select signal (117, 119, 121, 123) goes to a channel priority encoder (125).
