AI Technical Summary

Problems solved by technology

As a result, the number of times information is copied and transferred tends to increase in entertainment equipment, which is undesirable for entertainment equipment requiring high-speed processing
In addition, the time required for the CPU to wait for the I / O processor to process is also too long, which is not conducive to high-speed processing.

Abstract

An entertainment apparatus includes a storage unit which stores a device driver for a peripheral device outside a kernel. In order to make the peripheral device operable, a CPU causes an I O processor to execute the device driver based on a remote procedure call. Data transfer between the peripheral device and the CPU is performed by a direct memory access according to a communication protocol which is commonly used at least in the apparatus.

Description

technical field [0001] The present invention relates to an entertainment device capable of performing entertainment processing, including reproduction of sound and images, based on digital information recorded on a secondary storage medium such as a CD-ROM or DVD-ROM, and in particular relates to a device connected to the entertainment device control of peripheral devices on the Background technique [0002] An entertainment device implemented as an entertainment-dedicated computer that performs activities such as games performs given entertainment processing in cooperation with peripheral devices such as a controller connected to the entertainment device, an external storage medium, and the like. Specifically, entertainment devices perform given entertainment processing according to inputs from peripheral devices such as controllers and external storage media and output the results thereof to display units such as television receivers and speakers. Thus, for an entertainme...
