Reconfigurable pin-to-pin interface and how to set it up

Abstract

The invention discloses a reconfigurable pin-to-pin interface, comprising: a first channel circuit, used to obtain a first input signal transmitted through a first channel corresponding to the first channel circuit to obtain a second a received signal; and a second channel circuit for obtaining a second received signal by receiving a second input signal transmitted via a second channel corresponding to the second channel circuit; and a reconfiguration circuit, wherein when the When the second channel is used as a data channel and the first channel is used as a clock channel, the reconfiguration circuit is configured to redirect the first received signal to the second channel circuit for use as the second a clock input to a channel circuit; and preventing the second receive signal from being redirected to the first channel circuit to prevent the second receive signal from being used as a clock input to the first channel circuit.

Description

technical field [0001] The invention relates to the technical field of data transmission, and more specifically relates to a reconfigurable pin-to-pin interface and a setting method thereof. Background technique [0002] The camera interface may be a pin-to-pin interface provided between the first chip and the second chip to transfer multimedia data from the first chip to the second chip for further processing . For example, the first chip may include a camera module (module), and the second chip may include an image signal processor (ISP, image signal processor). Multimedia data may include image data (eg, a single captured image) or video data (eg, a video sequence of captured images). Usually, when a pin-to-pin interface is transmitting, a channel has been defined as a clock signal or a data signal, and cannot be changed. In this way, users can only transmit clock signals or data signals in a pre-designed way. For example, if one of the channels is set to transmit cloc...

Problems solved by technology

In this way, users can only transmit clock signals or data signals in a pre-designed way. For example, if one of the channels is set as a transmission clock channel, the user can only transmit clock signals through this channel, and cannot transmit data signals through this channel.

However, the needs of users in practical applications are changing. If users want to transmit data signals through this channel, they may need to redesign the pin-to-pin interface or replace it with other interfaces, which will increase the cost and cost more time to adapt the interface
