Glossary

C-8

N

nonmaskable interrupt (NMI):

An interrupt that can be neither masked nor

disabled.

O

object file:

A file that has been assembled or linked and contains machine

language object code.

off chip:

A state of being external to a device.

on chip:

A state of being internal to a device.

P

peripheral:

A device connected to and usually controlled by a host device.

program cache:

A fast memory cache for storing program instructions

allowing for quick execution.

program memory:

Memory accessed through the C6x’s program fetch

interface.

PWR:

Power; see PWR module.

PWR module:

PWR is an API module that is used to configure the

power-down control registers, if applicable, and to invoke various
power-down modes.

R

random-access memory (RAM):

A type of memory device in which the

individual locations can be accessed in any order.

register:

A small area of high speed memory located within a processor or

electronic device that is used for temporarily storing data or instructions.
Each register is given a name, contains a few bytes of information, and
is referenced by programs.

reduced-instruction-set computer (RISC):

A computer whose instruction

set and related decode mechanism are much simpler than those of
microprogrammed complex instruction set computers. The result is a
higher instruction throughput and a faster real-time interrupt service
response from a smaller, cost-effective chip.
