Abstract: PHN.11.771                   23               4.12.86 ABSTRACT: Method of and device for decoding a block of code symbols which is distributed between code words in two ways, each code word being protected by a maximum distance separable code.           A block of code symbols is protected by a product code or a pseudo product code. First of all, all syndrome symbols are formed and all code words having a syndrome which deviates from zero are provided with a flag. Each non-redundant symbol forms part of a first code word and also of a second code word, the numbers of flags of first and second code words being separately summed. The code words are successively addressed and an error location is determined. When an error location forms part of an incorrect first code word as well as of an incorrect second code word, it is corrected; if the second code word is not signalled as being incorrect, however, the error will not be corrected. After correction, the symdromes are updated, the flags being updated and the summing results being decremented only if the symdromes of both relevant code words are zero. In the opposite case the flags will remain unmodified for the time being.

Title: Microprocessor with selective cache memory
Inventor: BODDIE JAMES R
IPC: G06F12/08
Filed: 1987-08-27
Granted: 1991-09-17
Abstract: MICROPROCESSOR WITH SELECTIVE CACHE MEMORY            Abstract A signal processing system is described which has a processor, a random access memory for storage of data, a read-only memory for storage of both coefficients and instructions, and a selective cache memory for storage of instructions that require high performance, and their associated buses. Instructions selected by the program are stored in the selective cache memory during their first call from the read-only memory for use later in the program.  An address sequencer can be used as a control unit for executing the data stored in the selective cache memory.  It generates a sequence of addresses repetitively, counts the number of iterations of the sequence of addresses, and informs the controller when a certain number of iterations have been completed.  This creates a conditional branch statement in the program of the signal processing system.
