Modular signal processing unit
First Claim
1. A modular signal processing unit configured to reside on the Standard Electronics Module (SEM-E) circuit card specified by Military Standard MIL-STD-1389D, comprising:
- a plurality of unit input signal lines for receiving input data;
an input programmable gate array connected to said unit input signal lines for distributing the input data as distributed data on a plurality of processor input signal lines;
a plurality of floating point single chip digital signal processors (DSP), each of said plurality of single chip DSPs connected to a corresponding one of said plurality of processor input signal lines, each of said plurality of single chip DSPs processing the distributed data passed on said corresponding one of said plurality of processor input signal lines and outputting processed data on a corresponding one of a plurality of processor output signal lines;
an output programmable gate array connected to said plurality of processor output signal lines for organizing and outputting the processed data;
a plurality of unit output signal lines for transmitting the processed data from said output programmable gate array, wherein said plurality of unit input signal lines is equal to said plurality of unit output signal lines; and
a clock for controlling timing of said plurality of single chip DSPs, said input programmable gate array and said output programmable gate array.

Abstract
A modular signal processing unit capable of being connected in series, palel or combinations thereof, is provided. Each modular unit is a parallel signal processor that receives input data on a plurality of parallel-signal input lines and sends processed data on the same number of parallel-signal output lines. Each modular signal processing unit has an input gate array for distributing the input data, a plurality of current state-of-the-art single chip, digital signal processors (DSP) to process the distributed data, and an output gate array to organize the processed data onto the parallel-signal output lines. The modular signal processing unit is easily upgraded by replacing the single chip DSP'"'"'s as such technology improves.
