ABSTRACT:
A host device includes a peripheral control module that includes a first memory register that receives data from a first memory and a direct memory access (DMA) module that communicates with the first memory. The host device also includes a host control module that receives data from the first memory. The host device also includes a DMA control module that communicates with the first memory register, the host control module and a second memory that includes a first memory array. The DMA control module compares contents of the first memory array to contents of the memory register and controls transfers of data from the first memory to the peripheral control module based on the comparison.
