TMS320

TMS320 is a blanket name for a series of digital signal processors (DSPs) from Texas Instruments. It was introduced on April 8, 1983, through the TMS32010 processor, which was then the fastest DSP on the market.

The processor is available in many different variants, some with fixed-point arithmetic and some with floating-point arithmetic. The TMS320 processors were fabricated on MOS integrated circuit chips, including both NMOS and CMOS variants. The floating-point DSP TMS320C3x, which exploits delayed branch logic, has as many as three delay slots.^[1]

This series of processors are used as a digital signal processing co-processor and as the main CPU in some applications. Newer implementations support standard IEEE JTAG control for boundary scan and/or in-circuit debugging.

The original TMS32010 and its subsequent variants are an example of a CPU with a modified Harvard architecture, which features separate address spaces for instruction and data memory but the ability to read data values from instruction memory. The TMS32010 featured a fast multiply-and-accumulate operation useful in both DSP applications as well as transformations used in computer graphics. The graphics controller card for the Apollo Computer DN570 Workstation, released in 1985, was based on the TMS32010 and could transform 20,000 2D vectors per second.^{[clarification needed]}
