         TMS320 Family Overview
   The TMS320 family consists of fixed- and floating-point
    multiprocessor digital signal processors (DSPs), and
    fixed-point DSP controllers.
   TMS320 DSPs have an architecture designed
    specifically for real-time signal processing.
   The ’24x series of DSP controllers combines this real-
    time processing capability with controller peripherals to
    create an ideal solution for control system applications.
   Today, the TMS320 family consists of these generations:
    ’C1x, ’C2x, ’C20x, ’C24x, ’C5x,’C54x, and ’C6x fixed-
    point DSPs; ’C3x and ’C4x floating-point DSPs; and ’C8x
    multiprocessor DSPs.
   The following characteristics make the TMS320 family
    the right choice for a wide range of processing
    applications:

    TMS320C24x Series of DSP Controllers

   The ’F243/F241/C242 devices are considered part of
    the ’24x generation of fixed-point DSPs, and
    members of the ’C2000 platform.
   Devices within a generation of a TMS320 platform
    have the same CPU structure but different on-chip
    memory and peripheral configurations.
   At 20 Million Instructions Per Second (MIPS), the ’24x
    DSP controllers offer significant performance over
    traditional 16-bit microcontrollers and microproces-
    sors.
   Designers have recognized the opportunity to
    redesign existing digital motor control (DMC) systems
    to use advanced algorithms that yield better
    performance and reduce system component count.

    What The ’24x Series Enable?
   ’24x DSPs Enable:
     •   Design of robust controllers for a new generation of inexpensive
         motors, such as AC induction, DC permanent magnet, and switched-
         reluctance motors.
     •   Full variable-speed control of brushless motor types that have lower
         manufacturing cost and higher reliability.
     •   Energy savings through variable-speed control, saving up to 25% of
         the energy used by fixed-speed controllers.
     •   Elimination or reduction of memory lookup tables through real-time
         polynomial calculation, thereby reducing system cost.
     •   Use of advanced algorithms that can reduce the number of sensors
         required in a system.
     •   Control of power switching inverters, along with control algorithm
         processing.
     •   Single-processor control of multimotor systems.

            TMS320F243 DSK


   We will use the F243 Development Starter
    Kit (DSK) as a training tool.

Some Key Features of the F243 DSK


   TMS320F243 Digital Signal Processor.
   RS-232 Communications interface to
    host PC for debug and communications.
   32K words on board program/data RAM.
   8K words on chip Flash memory.
   On board 10 MHz crystal.
   3 Expansion Connectors (analog, I/O,
    expansion).

                      Mohammed Yousef Abd El ghany, Faculty of Eng., Comm. Dep. , 3rd year.
      How To Use The F243 DSK?

   Connect the device to the communication cable
    and the communication cable to the host PC.
   Install the communication software (GO DSP
    EXPLORER) in the host PC.
   Write your application program, debug, assemble,
    compile, and link it.
   Connect your peripherals hardware to the DSP and
    finally send the program to the device to run.
