ABSTRACT:
A data-processing system for pattern-recognition and the like, having an instruction unit (IU) for storing, decoding and modifying instructions, and an execution unit (EU) for storing and performing operations on data. The IU has facilities for making a branch address effective for a plurality of subsequent instructions, and for masking and de-conditioning the prospective branch. The IU also indexes data-operand addresses according to a variable modulus. The EU performs Boolean and voting logic functions in a series of cascaded registers. The EU controls the acquisition of external data according to the type of instruction being executed, and maintains a record of the location of data strings in memory. Intermediate computational results are automatically placed in a hardware stack without any programming overhead. Bits from multiple operands are placed in a single operand byte by shift-load instructions.
