Abstract
Abstract A programmable digital controller has an address matrix memory (20) and an instruction matrix memory (10). The address memory stores address words each having the address of the first sample and the number of samples in a unique group of samples. Unique groups of samples are sequentially stored in an instruction matrix memory. Each column of the instruction memory has data bits for regenerating an instruction set for controlling any one of many apparatus or processes. Each row of the instruction memory has a sample from each instruction set. In response to an enabling signal, the words from the address memory are sequentially read, interpreted, and the samples from the instruction memory caused to be read and for reconstructing the instruction set.

Claim 2
Dependent Claim
160 words
In a telephone or telecommunications system, a programmable digital controller for generating a plurality of instructions, said instructions being in bits, each of said instructions being used for controlling a separate apparatus or process, said controller comprising a first memory having previously entered therein said instructions in a matrix form, each column of said matrix comprising one of said instructions, each row of said matrix comprising one bit from each of said columns, each of a plurality of blocks of said rows having a unique bit pattern, each block appearing only once, a second memory comprising a plurality of addresses previously entered therein, each of said addresses comprising two parts: a first part indicating one of said rows of said first memory to be read initially and a second part indicating one of said blocks of said rows to be read consecutively, means for reading said addresses, and means responsive to said addresses for reading said blocks of said rows.
Claim 3
Dependent Claim
33 words
The controller of claim 1 wherein said addresses are read sequentially, a predetermined number of said blocks of said rows being read repeatedly according the to order in which said addresses are read.
Claim 4
Dependent Claim
54 words
The controller of claim 2 wherein said means for reading said addresses comprises means for counting clock pulses up to a predetermined number, means for decoding said predetermined number of clock pulses into one of said addresses, and means, responsive to said decoding means, for reading one of said addresses from said second memory.
Claim 5
Dependent Claim
75 words
The controller of claim 3 wherein said means responsive to said addresses for reading said blocks of said rows comprises means for decoding said addresses, means, responsive to said decoding means, for reading one of said rows to be read initially within said block of rows in said first memory, and means, responsive to clock pulses, for sequentially moving said means for reading said rows, one row at a time, within said block of rows.
Claim 6
Dependent Claim
130 words
In a telephone or telecommunications system, a programmable digital controller comprising a first memory having binary digits (bits) of information in matrix form, said matrix form having a plurality of columns and a plurality of rows, each of said columns having instructions for controlling a separate process or apparatus, each of said rows having one bit from each of said columns, each of a plurality of groups of said rows forming unique bit patterns, said groups being read according to a predetermined pattern, a binary counter, being indexed by clock pulses, providing the address of each of said rows, a decoder responsive to said binary counter for decoding said addresses, and a pointer, responsive to said decoder, for locating said row to be read selectively, one row at a time.
Claim 7
Dependent Claim
130 words
In a telephone or telecommunications system, a programmable digital controller comprising a first memory having binary digits (bits) of information in matrix form, said matrix form having a plurality of columns and a plurality of rows, each of said columns having instructions for controlling a separate process or apparatus, each of said rows having one bit from each of said columns, each of a plurality of groups of said rows forming unique bit patterns, said groups being read according to a predetermined pattern, a binary counter, being indexed by clock pulses, providing the address of each of said rows, a decoder responsive to said binary counter for decoding said addresses, and a pointer, responsive to said decoder, for locating said row to be read selectively, one row at a time.
Claim 8
Dependent Claim
127 words
