Abstract : A binary decision apparatus comprising a control unit which generates the binary decision apparatus' control signals from an operation code contained in the first byte of an instruction, a program counter which provides addressing for an external program memory, and a memory buffer register for holding digital instruction data provided by the external program memory. External control signals provided to the binary decision apparatus include a single phase system clock, a system reset signal and a wait signal that can be used to single-step the binary decision apparatus. Program instructions are provided from the external program memory to the binary decision apparatus via an eight-bit data bus, while an internal twel ve-bit data bus routes digital information between the registers and counters of the binary decision apparatus.
