Direct Memory Access (DMA)

• Direct Memory Access (DMA) provides an efficient

way to transfer data without using the CPU.

• It is very useful for transferring large blocks of data,

for example video and audio.

Data Transfer without DMA

• Without Direct Memory Access (DMA), any data

transfer has to be handled by the CPU.

Data Transfer with DMA

• With DMA, data values are transferred directly to

memory.

• This enables the CPU to allocates its resources for

other tasks.

* Single- and Double-Precision Instructions

* Byte-Addressable (8-, 16-, 32-Bit Data)

* 8-Bit Overflow Protection

* Saturation; Bit-Field Extract, Set, Clear; Bit-

Counting; Normalization
