Patent number: 6275504Abstract: A direct memory read and cell transmission apparatus for an ATM cell segmentation system having a host CPU is disclosed. The segmentation circuit of the apparatus transfers the address and size for the start of the DMA by the byte unit. When a predetermined information is provided, and a DMA read is requested, the data is transferred through the bus of the word unit such as the PCI interface, and then necessary bytes are obtained for thereby forming a 32 bit word stream, so that the ATM cell of a 32 bit×12 word form and transfers to the lower circuit. Therefore, when the segmentation circuit processes the buffer, all data are computed by the byte unit, and in an application program, the data are not obtained for transmitting the data to the ATM cell, so that it is possible to enhance the processing capability.Type: GrantFiled: August 24, 1998Date of Patent: August 14, 2001Assignees: Electronics and Telecommunications Research Institute, Korea TelecomInventors: Chan Kim, Jong Arm Jun, Kyou Ho Lee, Hyup Jong Kim, Jae Geun Kim
