DIRECT MEMORY ACCESS CONTROLLER AND A DATA TRANSMITTING METHOD OF DIRECT MEMORY ACCESS CHANNEL, CAPABLE OF REDUCING CONTROL LOAD OF PROCESSOR FOR TRANSMITTING BULK BLOCK DATA

摘要

PURPOSE: A direct memory access controller and a data transmitting method of direct memory access channel are provided to transmit bulk block data by controlling multiple DMA channels.;CONSTITUTION: A plurality of channel groups(220,230) have a plurality of DMA channels. The channel group controller(210) controls the activation of DMA channels to the channel group unit. The channel group controller activates the DMA channel of one or more channel groups in data transmission among a plurality of channel groups. The DMA channels of access channels offer the dual-port interface. The DMA channels are physically independent.;COPYRIGHT KIPO 2010
