The A236 Chip can easily use many types of digital image sensors. The logic sense of each of the video control signals is programmable by software in the A236 Chip. A single LCD can be driven by multiple A236 Chips. A small fpga can control the Output Enable signal of a DMA port of each of the A236 Chips so that digital video outputs from multiple A236 Chips can drive a single display device. In addition, the A236 Chip supports a two-wire Serial Bus .
Many image sensors use such a bus to initialize parameters that control the operation of the sensor.
The A236 Chip supports both progressive scan and interlaced video data. The A236 Chip supports many types of video data efficiently. For example, the SRGB color mosaic data shown above can easily be converted into four arrays where all of the pixels in each array are closely related to one another. This has many uses including motion estimation for image compression and the pasting of groups of pixels into memory for image decompressoin. The A236 Chip can simultaneously implement four adjacent and partially overlapping 2 x 2 windows that slide horizontally and vertically through the image.
