Glossary

C-2

board support library (BSL):

The BSL is a set of application programming

interfaces (APIs) consisting of target side DSP code used to configure
and control board level peripherals.

boot:

The process of loading a program into program memory.

boot mode:

The method of loading a program into program memory. The

C6x DSP supports booting from external ROM or the host port interface
(HPI).

BSL:

See board support library.

byte:

A sequence of eight adjacent bits operated upon as a unit.

cache:

A fast storage buffer in the central processing unit of a computer.

cache controller:

System component that coordinates program accesses

between CPU program fetch mechanism, cache, and external memory.

CCS:

Code Composer Studio.

central processing unit (CPU):

The portion of the processor involved in

arithmetic, shifting, and Boolean logic operations, as well as the
generation of data- and program-memory addresses. The CPU includes
the central arithmetic logic unit (CALU), the multiplier, and the auxiliary
register arithmetic unit (ARAU).

chip support library (CSL):

The CSL is a set of application programming

interfaces (APIs) consisting of target side DSP code used to configure
and control all on-chip peripherals.

clock cycle:

A periodic or sequence of events based on the input from the

external clock.

clock modes:

Options used by the clock generator to change the internal

CPU clock frequency to a fraction or multiple of the frequency of the input
clock signal.

code:

A set of instructions written to perform a task; a computer program or

part of a program.

coder-decoder or compression/decompression (codec):

A device that

codes in one direction of transmission and decodes in another direction
of transmission.

compiler:

A computer program that translates programs in a high-level

language into their assembly-language equivalents.
