Glossary

A-8

P

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.

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 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.

S

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.
