An image processing chip and an image processing system are provided. The image processing chip includes a first image end, a second image end, an image processing block and a multiplexer. The first image end receives at least one first image data packet. The image processing block is used to convert the at least one first image data packet into at least one second image data packet. The multiplexer has a first input end coupled to the first image end, a second input end coupled to the image processing block, and an output end coupled to the second image end. When the image processing chip operates in a first mode, the multiplexer is coupled to the first input end and the output end to transmit the at least one first image data packet from the first image end to the second image through the multiplexer.

Image processing chip and image processing system

The invention provides a method of managing SDIO commands at a host device and a peripheral device. The host device connected to the peripheral device by a bus comprising a command transmission line and a data transmission line, both of which are arranged to transmit single end signal. The host device converts operation requests into converted commands and combines a first SDIO complied data packet with the converted commands to generate a first combined data packet. Then, the host device transmits the first combined data packet through the data transmission line, wherein the first combined data packet comprises a first header for indicating whether the first combined data packet comprises the converted commands. After receiving the first combined data packet, the peripheral device parses the first combined data packet to obtain the converted commands, and then performs processing procedures according to the converted commands.

Peripheral device complying with SDIO standard and method for managing SDIO command

A method for receiving data with a secure digital input/output (SDIO) interface, which is utilized for providing a data transmission connection between a master device and a slave device, starts with receiving a first packet of the data from the slave device. The first packet is transferred with a plurality of data blocks. A first data block of the plurality of data blocks has reception information of a second packet. The method then generates a control signal to receive the second packet from the slave device according to the reception information of the second packet, which is a next packet of the first packet in the data.
