Original Abstract Submitted
aspects disclosed in the detailed description include a processing unit (pu) employing micro-operations (micro-ops) random access memory (ram) as main program memory. the micro-ops ram comprises row circuits each associated with a micro-op and configured to store control signal parameters and output ports configured to be coupled to a register file and one or more execution units. in contrast to fetching and decoding instructions of an isa in a conventional pu, the processing unit loads a main program comprising micro-ops into the row circuits of the micro-ops ram. when executing an individual micro-op of the main program, the processing unit activates a row circuit in the micro-ops ram to cause its stored control signal parameters to be communicated through the output ports of the micro-ops ram to the register file and/or the one or more execution units and avoids the need for a decoding stage circuit, advantageously decreasing processing latency.
