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.
