Glossary

A-8

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

program cache: A fast memory cache for storing program instructions al-

lowing for quick execution.

program memory: Memory accessed through the C6x’s program fetch in-

terface.

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.

random-access memory (RAM): A type of memory device in which the

individual locations can be accessed in any order.

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 micro-

programmed 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.

reset: A means of bringing the CPU to a known state by setting the registers

and control bits to predetermined values and signaling execution to start

at a specified address.

RTOS Real-time operating system.

structure: A collection of one or more variables grouped together under a

single name.

synchronous-burst static random-access memory (SBSRAM): RAM

whose contents does not have to be refreshed periodically. Transfer of

data is at a fixed rate relative to the clock speed of the device, but the

speed is increased.
