TMS320 DSP have an architecture designed specifically for realtime signal processing . The’ F/C240 is a number of the’C2000DSP platform , and is optimized for control applications. The’C24x series of DSP controllers bines this realtime processing capability with controller peripherals to create an ideal solution for control system applications. The following characteristics make the TMS320 family the right choice for a wide range of processing applications: Very flexible instruction set Inherent operational flexibility Highspeed performanceInnovative parallel architectureCost effectivenessDevices within a generation of the TMS320 family have the same CPU structure but different onchip memory and peripheral configurations. Spinoff devices use new binations of Onchip memory and peripherals to satisfy a wide range of needs in the worldwide electronics market. By integrating memory and peripherals onto a single chip , TMS320 devices reduce system costs and save circuit board space.The 16bit ,fixedpoint DSP core of the ‘C24x devices provides analog designers a digital solution that does not sacrifice the precision and performance of their 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 controller offer reliability and programmability . Analog control systems, on the other hand ,are hardwired solutions and can experience performance degradation due to aging , ponent tolerance, and drift.The highspeed central processing unit (CPU) allows the digital designer to process algorithms in real time rather than approximate results with lookup tables. The instruction set of these DSP controllers, which incorporates both signal processing instructions and generalpurpose control functions, coupled with the extensive development time and provides the same ease of use as traditional 8and 16bit microcontrollers. The instruction set also allows you to retain your software investment when moving from other generalpurpose‘C2xx generation ,source code patible with the’C2x generation , and upwardly source code patible with the ‘C5x generation of DSPs from Texas Instruments.The ‘C24x architecture is also wellsuited for processing control signals. It uses a 16bit word length along with 32bit registers for storing intermediate results, and has two hardware shifters available to scale numbers independently of the CPU . This bination minimizes quantization and truncation errors, and increases p2ocessing power for additional functions. Such functions might include a notch filter that could cancel mechanical resonances in a system or an estimation technique that could eliminate state sensors in a system.The ‘C24xDSP controllers take advantage of an 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 mixedsignal peripherals includes:TimersSerial munications ports (SCI,SPI)Analogtodigital converters(ADC)Event managerSystem protection, such as lowvoltage and watchdog timerThe DSP controller peripheral library is continually growing and changing to suit the of tomorrow’s embedded control marketplace.The TMS320F/C240 is the first standard device introduced in the ‘24x series of DSP controllers. It sets the standard for a singlechip digital motor controller. The ‘240 can execute 20 MIPS. Almost all instructions are executed in a simple cycle of 50 ns . This high performance allo
