摘要： An interface unit 20 assigns different SDRAMs 1 and 2 to adjacent drawing blocks in a frame-buffer area. In processing that extends across the adjacent drawing blocks, active commands, for example, are issued alternately to the SDRAMs 1 and 2 to reduce waiting cycles resulting from the issue interval restriction. Furthermore, since individual clock enable signals CKE1 and CKE2 are output to the SDRAMs 1 and 2 so that burst transfers of the SDRAMs 1 and 2 can be stopped individually, no cycle is necessary to stop the burst transfers.

摘要： The data transfer device for transferring data between a system bus and a local memory having a frame buffer region and a general region includes an interface section and a data processor. The interface section generates a transfer parameter for accessing one of the frame buffer region and the general region based on control data for controlling data transfer sent from the system bus and outputs the generated transfer parameter, in addition to transferring data to/from the system bus. The data processor generates an address of data to be transferred in the local memory according to the transfer parameter, and transfers data to/from the local memory using the generated address, in addition to transferring data to/from the interface section.

摘要： A computer system which significantly improves responsiveness to a sleep request includes: a processor device switching between an execution mode and a suspension mode; and an access controlling unit accessing a functional block in response to a command request received from the processor device, wherein, in response to a sleep request signal received from the external device, the processor device responds with a sleep response signal and asserts a suspension notification signal indicating a switch to the suspension mode, and the access controlling unit: masks an input of a further command request after receiving the command request from the processor device, in the case where the processor device has outputted the command request when the access controlling unit receives the suspension notification signal; masks an input of a command request in the case where the processor device has not outputted the command request; and removes the mask when the suspension notification signal is negated.

摘要： A multithreaded computer system of the present invention includes a plurality of processor elements (PEs) and a parallel processor controller which switches threads in each PE. The parallel processor controller includes a plurality of execution order registers which hold, for each processor element, an execution order of threads to be executed; a plurality of counters which count an execution time for a thread that is being executed by each processor element and generate a timeout signal when the counted time reaches a limit assigned to the thread; and a thread execution scheduler which switches the thread that is being executed to the thread to be executed by each processor element based on an execution order held in the execution order register and the timeout signal.
