F24x 16-bit Series
|
The TMS320C24x is a member of the TMS320 family of digital signal processors (DSPs). The ’C24x is designed to meet a wide range of digital motor control (DMC) and embedded control applications.
The ’C24x DSP controllers are designed to meet the needs of control-based applications. By integrating the high performance of a DSP core and the on-chip peripherals of a microcontroller into a single-chip solution, the ’C24x series yields a device that is an affordable alternative to traditional microcontroller units (MCUs) and expensive multichip designs. At 20 million instructions per second (MIPS), the ’C24x DSP controllers offer significant performance over traditional 16-bit microcontrollers and microprocessors. Future derivatives of these devices will run at speeds higher than 20 MIPS.
The 16-bit, fixed-point DSP core of the ’C24x device provides analog designers a digital solution that does not sacrifice the precision and performance of 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 hardwired solutions and can experience performance degradation due to aging, component tolerance, and drift.
The ’C24x DSP architecture is based on a modified Harvard architecture, which supports separate bus structures for program space and data space. A third space, the input/output (I/O) space, is also available and is accessible through the external bus interface. To support a large selection of peripherals, a peripheral bus is used. The peripheral bus is mapped to the data space and interfaced to the data bus through a special system module. Thus, all the instructions that operate on the data space also operate on all the peripheral registers.
Separate program and data spaces allow simultaneous access to program instructions and data. For example, while data is multiplied, a previous product can be added to the accumulator, and at the same time, a new address can be generated. Such parallelism supports a set of arithmetic, logic, and bit-manipulation operations that can all be performed in a single machine cycle. The ’C24x also includes control mechanisms to manage interrupts, repeated operations, and function/subroutine calls. |
