The TMS32010 digital signal processor (DSP), introduced in 1983, was the first DSP in the TMS320 family. From it has evolved this TMS320C1x generation of 16-bit DSPs. All C1x DSPs are object code compatible with the TMS32010 DSP. The C1x DSPs combine the flexibility of a high-speed controller with the numerical capability of an array processor, thereby offering an inexpensive alternative to multichip bit-slice processors. The highly paralleled architecture and efficient instruction set provide speed and flexibility to produce a CMOS microprocessor generation capable of executing up to 8.77 MIPS (million instructions per second) (C16). These C1x devices utilize a modified Harvard architecture to optimize speed and flexibility, implementing functions in hardware that other processors implement through microcode or software. The C1x generation's powerful instruction set, inherent flexibility, high-speed number-handling capabilities, reduced power consumption, and innovative architecture have made these cost-effective DSPs the ideal solution for many telecommunications, computer, commercial, industrial, and military applications. This data sheet provides detailed design documentation for the C1x DSPs. It facilitates the selection of devices best suited for various user applications by providing specifications and special features for each C1x DSP. This data sheet is arranged as follows: introduction, quick reference table of device parameters and packages, summary overview of each device, architecture overview, and the C1x device instruction set summary. These are followed by data sheets for each C1x device providing available package styles, terminal function tables, block diagrams, and electrical and timing parameters. An index is provided to facilitate data sheet usage.
