摘要: The data processor for processing operation data stored in a memory connected to an external bus in the order of operations includes: an interface section for holding a parameter required for transfer of the operation data; an operation section receiving the operation data from the interface section for performing predetermined processing; and an operation memory for storing the operation data transferred. The interface section sequentially transfers the operation data from the memory connected to the external bus to the operation memory using the parameter, and sequentially transfers the operation data from the operation memory to the operation section.

摘要: A transfer request processing portion 10 confirms the kind of requested data and sets, in a transfer mode setting portion 11, a transfer mode for respectively allocating a first data buffer 16 to a first DMAC 12 and a second data buffer 17 to a second DMAC 13 when parallel data transfer is necessary, or a transfer mode for allocating both of the first data buffer 16 and the second data buffer 17 to the first DMAC 12 or the second DMAC 13 that has been started at that time when parallel data transfer is not necessary. The first DMAC 12 and/or the second DMAC 13 performs data transfer by using the data buffer instructed by the transfer mode.

摘要: The rendering performance of a graphic processor is improved by effectively using a data bus. An externally-input graphics command is stored in a work memory via the data bus. A display data generation section receives a graphics command stored in the work memory via the data bus, decodes the received graphics command, and outputs the display data to the data bus. An image display section receives display data stored in the work memory via the data bus, and displays an image on a display device. A bus control section monitors the status of use of the data bus, and controls the right to use the data bus according to the priority of each data transfer operation.
