Product Summary

The TMS320E15JDL 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 TMS320E15JDL 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). The TMS320E15JDL utilizes a modified Harvard architecture to optimize speed and flexibility, implementing functions in hardware that other processors implement through microcode or software.
