The processor is available in many different variants, some with fixed-point arithmetic and some with floating point arithmetic. The floating point DSP TMS320C3x, which exploits delayed branch logic, has as many as three delay slots.
The flexibility of this line of processors has led to it being used not merely as a co-processor for digital signal processing but also as a main CPU. They all support standard IEEE JTAG control for development.
The original TMS32010 and its subsequent variants is 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 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/second.
The TMS320 architecture has been around for a while so a number of product variants have developed. The product codes used by Texas Instruments after the first TMS32010 processor have involved a very popular series of processor named TMS320Cabcd where a is the main series, b the generation and cd is some custom number for a minor sub-variant.
For this reason people working with DSPs often abbreviate a processor as "C5x" when the actual name is something like TMS320C5510, since all products obviously have the name "TMS320" and all processors with "C5" in the name are code compatible and share the same basic features. Sometimes you will even hear people talking about "C55x" and similar subgroupings, since processors in the same series and same generation are even more similar.

The TMS320 series can be programmed using C, C++, and/or assembly language. Most work on the TMS320 processors is done using Texas Instruments proprietary toolchain and their integrated development environment Code Composer Studio, which includes a mini operating system called DSP/BIOS. Additionally, a department at the Chemnitz University of Technology has developed preliminary support for the TMS320C6x series in the GNU Compiler Collection. In November 2007 TI took steps towards a free software release of its toolchain by offering the bare compiler, assembler, optimizer and linker to non-commercial users. However, neither the IDE nor a debugger were included, so for debugging and JTAG access to the DSPs, users still need the proprietary toolchain.
