An imaging system may include a multi-channel image sensor. In a multi-channel image sensor, multiple image streams from a common pixel array may be provided to a common interface transport for output on multiple logic channels. Image streams may include high-definition (HD) video and snapshot image data. Video image data may be resized using resize circuitry on the image sensors. Snapshot image data may be processed by the image sensor. Full-resolution portions of snapshot images may be output concurrently with resized HD video image data on multiple logic channels to an image signal processor. In an alternative embodiment, stack memory on the image sensor may be used to store full-resolution snapshot image data. Full-resolution snapshot image data may then be output concurrently with resized HD video image data at a slower data rate than the video image data.

Microprocessor development systems

In order to smooth the entry into a debugging operation using a scan chain of registers in a microprocessor, a method for carrying out debugging procedures. The method comprises providing a processor with a chain of scan registers, a scan interface for interfacing with an external scan controller, a breakpoint interrupt mechanism for executing an interrupt instruction, and a processor clock control mechanism. The method includes detecting or generating a breakpoint in the operation of the processor. The breakpoint interrupt mechanism executes an interrupt instruction as a result of which the processor completes its current instruction, and signals the same to the scan interface. The scan interface asserts a Start Scan signal to the clock signal control mechanism, which whereupon stops the processor clock or clocks. The external scan controller is alerted to start a scan sequence.
