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).
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.
external interrupt: A hardware interrupt triggered by a specific value on a
pin.
external memory interface (EMIF): Microprocessor hardware that is used
to read to and write from off-chip memory.
fetch packet: A contiguous 8-word series of instructions fetched by the CPU
and aligned on an 8-word boundary.
flag: A binary status indicator whose state indicates whether a particular
condition has occurred or is in effect.
frame: An 8-word space in the cache RAMs. Each fetch packet in the cache
resides in only one frame. A cache update loads a frame with the re-
quested fetch packet. The cache contains 512 frames.
