Machine Architecture Computing Science and Mathematics. A complex instruction set computer (CISC / ˈ s ɪ s k /) is a computer in which single instructions can execute several low-level operations (such as a load from memory, an arithmetic operation, and a memory store) or are capable of multi-step operations or addressing modes within single instructions., Data General later switched architectures and became an early supporter of the Motorola 88K series load-store microprocessor in the AViiON Unix based systems (rumour had it that designers originally wanted to call it the Nova II, but that idea was rejected, so instead they reversed the name and inserted the II in the middle, switching upper and lower case. In reality, there had already been.

The descriptor table entry for the selector contains the data for the register. The DS and ES registers can be loaded with a null selector without causing an exception. Use of DS or ES however, causes a #GP(0), and no memory reference occurs. All interrupts are inhibited until after the execution of the next instruction, after a movw into SS Data General's MicroNOVA MP/100 is an example of their second- generation microprocessor NOVA implementations. The CPU is implemented on a single VLSI (Very Large Scale Integration) IC capable of executing the basic NOVA instruction set with a few additional op-codes.
