Abstract
A programmable versatile digital signal processing system architecture (FIG. 5) allows the implementation of functions for transmitting and receiving a variety of narrow and wide-band communication signaling schemes. The flexibility of the architecture (FIG. 5) makes it possible to receive and transmit many different spectral communication signals in real time by implementing signal processing functions such as filtering, spreading, de-spreading, rake filtering, and equalization under the direction of program instructions (1300, 1400, 1500, 1600).
Claims20
A hybrid instruction set for programming a versatile digital signal processing system, comprising:
- a program instruction word, comprising:
- an operation code field;
- a loop counter field responsive to the operation code field;
- and
- a cycles/location field responsive to the operation code field and the loop counter field;
- wherein the program instruction word operates to establish one of a plurality of unique program instruction words, each of the plurality of program instruction words representing a distinct instruction that selectively configures programmable hardware for executing digital signal processing functions.
