Patent number: 6567908Abstract: An information processing apparatus has a DRAM for storing at least predetermined data, a system bus to which the DRAM is connected, a CPU for controlling the DRAM, and a CPU bus to which the CPU is connected. The information processing apparatus also has an SRAM connected to the system bus and the CPU bus, for storing data transferred from the DRAM, an address counter for generating an address of the SRAM based on an initial value, and a DMA controller for controlling data transfer between the DRAM and the SRAM using the address generated by the address counter. At a certain time, the DMA controller outputs an address D2 next to an initial address in the DRAM via the system bus to the DRAM, reads data B from the address D2, and outputs the data B via the system bus to the SRAM. At the same time, the address counter increments a stored address S1 into an address S2, and outputs the address S2 to the SRAM, which stores the data B at the address S2.Type: GrantFiled: July 2, 1999Date of Patent: May 20, 2003Assignee: Sony Computer Entertainment Inc.Inventor: Makoto Furuhashi
