5. The programmable filter processor as recited in claim 1 , wherein predetermined functions are implemented in hardware within the logic unit, by which the programmable filter processor is adaptable to predetermined signal processing tasks.

6. The programmable filter processor as recited in claim 1 , wherein a plurality of working registers is implemented in the logic unit, which buffer-store partial results.

7. The programmable filter processor as recited in claim 1 , wherein the programmable filter processor is adapted to work with one data set, and, in parallel, to load an additional data set into the first memory of the programmable filter processor.

8. The programmable filter processor as recited in claim 1 , further comprising:

a predictor-corrector arrangement to determine the different software algorithms.

9. The programmable filter processor as recited in claim 8 , wherein the predictor-corrector arrangement includes a trigger line.

10. The programmable filter processor as recited in claim 1 , further comprising:

a first in first out (“FIFO”) buffer connected to the second memory.
