Abstract
A pipelined processing unit which includes an instruction unit stage containing logic management apparatus for processing a set of complex instructions. The logic management apparatus includes state control circuits which produce a series or sequence of control states used in tracking the different types of instructions of the complex instruction set being processed. Different ones of the states are used for different types of instructions so as to enable the different pipeline stages to operate both independently and jointly to complete the execution of different instructions of the complex instruction set.
