Glossary

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.

C

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.
