Glossary

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.
