Disclosed is a digital computer whose structure is programmable. As a result, the computer\s data section, which transforms operands in response to control word sequences, can be readily changed to interpret different types of control words. This is to be distinguished from merely changing the sequence of some fixed set of control words in a control memory. The disclosed programmable structure also enables the computer\s control section, which generates the control word sequences, to be readily modified to perform different types of branches as opposed to branches of some rigidly fixed set.

A digital computer having a control section for sequentially generating addresses to a control memory from digital data of any kind, said control section being comprised of: a plurality of programmable memory means, each of said memory means having first address inputs, second address inputs coupled

A digital computer having a control section for sequentially generating addresses to a control memory from digital data of any kind, said control section being comprised of: a plurality of programmable memory means, each of said memory means having first address inputs, second address inputs coupled to receive a portion of the presently active control word from said control memory, and a pair of outputs; a plurality of register means for storing said digital data, each of said register means having its ith bit coupled to the first address inputs on the ith one of said memory means, where i=1, 2 . . . N, N being the total number of programmable memory means; each of said memory means including means responsive to the control word portion on its second address inputs for generating signals on its pair of outputs representing programmable arithmetic transformations of the bits on its first address inputs; and means for combining said signals on said pair of outputs from all of said memory means into said control memory address.
