Glossary

A-4

device ID: Configuration register that identifies each peripheral component

interconnect (PCI).

digital signal processor (DSP): A semiconductor that turns analog sig-

nals—such as sound or light—into digital signals, which are discrete or

discontinuous electrical impulses, so that they can be manipulated.

DIP: The DIP Switches API Module.

direct memory access (DMA): A mechanism whereby a device other than

the host processor contends for and receives mastery of the memory bus

so that data transfers can take place independent of the host.

DMA : See direct memory access.

DMA module: DMA is an API module that currently has two architectures

used on C6x devices: DMA and EDMA (enhanced DMA). Devices such

as the 6201 have the DMA peripheral, whereas the 6211 has the EDMA

peripheral.

DMA source: The module where the DMA data originates. DMA data is read

from the DMA source.

DMA transfer: The process of transferring data from one part of memory to

another. Each DMA transfer consists of a read bus cycle (source to DMA

holding register) and a write bus cycle (DMA holding register to destina-

tion).

DSK: Digital signal processor (DSP) starter kit. Tools and documentation

provided to new DSP users to enable rapid use of the product.

EDMA: Enhanced direct memory access; see EDMA module.

EDMA module: EDMA is an API module that currently has two architectures

used on C6x devices: DMA and EDMA (enhanced DMA). Devices such

as the 6201 have the DMA peripheral, whereas the 6211 has the EDMA

peripheral.

EMIF: See external memory interface; see also EMIF module.

EMIF module: EMIF is an API module that is used for configuring the EMIF

registers.

evaluation module (EVM): Board and software tools that allow the user to

evaluate a specific device.
