Problems solved by technology

The improvement of the storage capacity of embedded devices can be achieved by replacing new large-capacity memory cards, but more efficient and more complex audio and video codecs have higher and higher requirements for host performance. By upgrading multimedia information on the basis of original hardware devices Processing software often fails to meet the requirements of real-time processing of multimedia information, so the improvement of multimedia information processing capabilities of terminal equipment is often achieved by replacing the embedded host. The disadvantage of this upgrading method is high cost and long cycle

Abstract

The invention discloses SDIO (secure digital input output) interface based multimedia information coprocessing equipment and a communication method thereof. The equipment comprises an external interface module, a master control module, a multimedia information coprocessor and a flash medium, wherein the master control module is respectively connected with the external interface module, the flash medium and the multimedia information coprocessor, and the multimedia information coprocessor is also connected with the flash medium. The communication method comprises: data is transmitted between the multimedia coprocessing equipment and a host machine provided with an SDIO interface, and whether the transmitted data is to be processed by the multimedia information coprocessor is determined according to the analysis carried out on a received command by the master control module. In the invention, by means of the SDIO interface of an embedded device, a high speed hardware architecture is taken as a basis to overcome the defect that the multimedia signal processing capacity of the host machine based on a universal processor is insufficient, and the rapid and effective upgrading of the equipment is realized with low cost.

Description

technical field [0001] The invention relates to a multimedia information co-processing device, in particular to a multimedia information co-processing device based on an SDIO interface and a communication method thereof. Background technique [0002] At present, consumer electronics technology is advancing by leaps and bounds, and new products are emerging in an endless stream. At the same time, the SD card jointly developed by Panasonic, Toshiba and SanDisk in August 1999 (this article refers to cards of various specifications whose interface conforms to the SD specification, including MMC Card, Mini SD card and Micro SD card) are widely used in mobile phones, digital cameras, walkmans, PDAs, e-books, set-top boxes, tablet computers and other products due to their small size, fast access speed, and large storage capacity. According to the purpose of SD card, SD card can be divided into three types: SD memory card, SDIO card (Secure Digital Input and Output Card) and SD Comb...
