摘要:
Coprocessor systems for using a main microprocessor DMA channel to write to a port to control a coprocessor system are provided. In certain examples, coprocessor systems are described using a main CPU counter to trigger a DMA channel to perform a single byte transfer to a port used to control coprocessor command timing.
