their systems. In fact, system performance can be enhanced through the use

of advanced control algorithms for techniques such as adaptive control,

Kalman filtering, and state control. The ’C24x DSP controllers offer reliability

and programmability. Analog control systems, on the other hand, are hard-

wired solutions and can experience performance degradation due to aging,

component tolerance, and drift.

The high-speed central processing unit (CPU) allows the digital designer to

process algorithms in real time rather than approximate results with look-up

tables. When the instruction set of these DSP controllers (which incorporates

both signal processing instructions and general-purpose control functions) is

coupled with the extensive development support available for the ’C24x de-

vices, it reduces development time and provides the same ease of use as tra-

ditional 8- and 16-bit microcontrollers. The instruction set also allows you to

retain your software investment when moving from other general-purpose

TMS320 fixed-point DSPs. It is source- and object-code compatible with the

other members of the ’C24x generation, source code compatible with the ’C2x

generation, and upwardly source code compatible with the ’C5x generation of

DSPs from Texas Instruments.

The ’C24x architecture is also well-suited for processing control signals. It

uses a 16-bit word length along with 32-bit registers for storing intermediate

results, and has two hardware shifters available to scale numbers indepen-

dently of the CPU. This combination minimizes quantization and truncation

errors, and increases processing power for additional functions. Two exam-

ples of these additional functions are: a notch filter that cancels mechanical

resonances in a system, and an estimation technique that eliminates state

sensors in a system.

The ’C24x DSP controllers take advantage of an existing set of peripheral

functions that allow Texas Instruments to quickly configure various series

members for different price/performance points or for application optimization.

This library of both digital and mixed-signal peripherals includes:

- Timers

- Serial communications ports (SCI, SPI)

- Analog-to-digital converters (ADC)

- Event manager

- System protection, such as watchdog timers

- CAN controller

The DSP controller peripheral library is continually growing and changing to

suit the needs of tomorrow’s embedded control marketplace.
