processor does something else. DMA is the fastest method of transferring
data to/from computer memory.
DNL
Differential nonlinearity—A measure in LSB of the worst-case deviation of
code widths from their ideal value of 1 LSB.
DO
Digital output.
E
EEPROM
Electrically erasable programmable read-only memory—ROM that can be
erased with an electrical signal and reprogrammed.
F
FPGA
Field-Programmable Gate Array.
FPGA VI
A configuration that is downloaded to the FPGA and that determines the
functionality of the hardware.
G
glitch
An unwanted signal excursion of short duration that is usually unavoidable.
H
