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.

E

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.
