Device and processing architecture for resolving execution pipeline dependencies without requiring no operation instructions in the instruction memory

Abstract

Different processor architectures are described to evaluate and track dependencies required by instructions. The processors may hold or queue instructions that require output of other instructions until required data and resources are available which may remove the requirement of NOPs in the instruction memory to resolve dependencies and pipeline hazards. The processor may divide instruction data into bundles for parallel execution and provide speculative execution. The processor may include various components to implement an evaluation unit, execution unit and termination unit.
