OPERATION
The MA2910 is a SOS microprogram controller intended for use in high speed microprocessor applications. Besides the capability of sequential access, it provides conditional branching to any microinstruction within its 4096-microword range. A last-in, first-out stack provides microsubroutine return linkage and looping capability; there are nine nesting levels of microsubroutines. Microinstruction loop count control is provided with a count capacity of 4096. The device is controlled by 16, 4-bit microinstructions. The PLA decodes the microinstructions on I(3:P) and produces select control codes for the multiplexer, register/counter, microprogram counter register, and stack. The 4-bit microinstructions also generate three active low enable signals (PL, VECT, and MAP) for external use....
