Glossary

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.

codec: Coder-decoder, or compression/decompression. A device that codes in one direction of transmission and decodes in another direction of transmission.

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 lan- guage into their assembly-language equivalents.

compress and expand (compand): A quantization scheme for audio sig- nals in which the input signal is compressed and then, after processing, is reconstructed at the output by expansion. There are two distinct com- panding schemes: A-law (used in Europe) and ∝ -law (used in the United States).

constant: A fixed or invariable value or data item that can be used as an op- erand.

control register: A register that contains bit fields that define the way a de- vice operates.

control register file: A set of control registers.

CSL: See chip support library.

CSL module: The CSL module is the top-level CSL API module.It interfaces to all other modules and its main purpose is to initialize the CSL library.

D

DAT: Data; see DAT module.

DAT module: The DAT is an API module that is used to move data around by means of DMA/EDMA hardware. This module serves as a level of ab- straction that works the same for devices that have the DMA or EDMA peripheral.

This allows for the simultaneous execution of multiple instructions, leading to enhanced processing speeds. The architecture is designed to support both fixed-point and floating-point operations, offering flexibility for different computational requirements. The use of VLIW (Very Long Instruction Word) technology allows the execution of multiple operations in a single instruction cycle, further maximizing performance.

The TMS320C6000 family utilizes high-speed memory architectures, including a sophisticated cache system that minimizes memory access delays. Built-in hardware accelerators for specific functions, such as fast Fourier transforms (FFTs) and filter algorithms, streamline processing tasks that are critical in real-time applications. The DSPs also support a range of data formats, enabling them to handle diverse data types efficiently.

An important aspect of the TMS320C6000 series is its scalability. The family includes a wide range of devices, from low-power processors suitable for portable equipment to high-performance models designed for demanding computation tasks. This scalability ensures that developers can select the appropriate DSP for their specific application requirements.

In terms of power efficiency, the TMS320C6000 processors are designed to deliver high performance with optimized power consumption. This makes them ideal for battery-operated devices where power management is a critical concern. Additionally, TI's software tools, such as Code Composer Studio, provide developers with an integrated development environment that simplifies the design process and enhances productivity.

Lastly, the extensive support for various communication interfaces, including PCI, USB, and Ethernet, allows for seamless integration into existing systems. With a rich ecosystem of hardware and software support, the TMS320C6000 series remains a popular choice for engineers seeking powerful and versatile DSP solutions in modern electronic design.
