Glossary

A-2

block:

The three least significant bits of the program address. These corre-

spond to the address within a fetch packet of the first instruction being
addressed.

BOARD:

The BOARD-specific API Module.

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 module:

CACHE is an API module containing a set of functions for

managing data and program cache.

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 genera-
tion of data- and program-memory addresses. The CPU includes the
central arithmetic logic unit (CALU), the multiplier, and the auxiliary regis-
ter arithmetic unit (ARAU).

CHIP:

See CHIP module.

CHIP module:

The CHIP module is an API module where chip-specific and

device-related code resides. CHIP has some API functions for obtaining
device endianess, memory map mode if applicable, CPU and REV IDs,
and clock speed.

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.
