Abstract
A microcontroller includes a direct memory access unit that compresses and decompresses data and transfers from one block of memory to another. Specifically, word size data can be read, one byte discarded, and stored as consecutive, byte size data. This can be used in conjunction with an extended read and extended write asynchronous serial port that stores status information along with data. Once the status information is processed, the status is stripped by performing the “compressive” DMA.
