  • Method and apparatus for hazard detection and management in a pipelined digital processor
    Publication number: 20040158694
    Abstract: Methods and apparatus are provided for use in a digital processor having a pipeline for executing instructions. The method includes monitoring instructions in the pipeline for instructions that write to a resource and instructions that read from the resource; for each instruction that writes to the resource, storing a write instruction type and write instruction tracking data; for each instruction that reads from the resource, determining a read instruction type and generating a latency value based on the write instruction type and the read instruction type; and stalling execution of the instruction that reads from the resource by a number of stall cycles in response to the latency value and the write instruction tracking data.
