Abstract
A data processing system having separate kernel, vertical and horizontal microcode, separate loading of vertical microcode and a permanently resident kernel microcode, and a soft console with dual levels of capability. The system includes a processor having dual ALC and microcode processors, and an instruction processor. Also included are a processor incorporating a multifunction processor memory, a multifunction nibble shifter, and a high speed look-aside memory control. Adaptive microcode control means 272 are disclosed in which microinstruction sequencing is a function 273 of the current microinstruction and current machine state.
