PARKING THREADS IN BARREL PROCESSOR FOR MANAGING HAZARD CLEARING - A simplified explanation of the abstract
This abstract first appeared for US patent application 17897926 titled 'PARKING THREADS IN BARREL PROCESSOR FOR MANAGING HAZARD CLEARING
Simplified Explanation
Devices and techniques for parking threads in a barrel processor for managing hazard clearing are described herein. A barrel processor includes hazard management circuitry that is used to receive an indication of an instruction executing in a compute pipeline of the barrel processor, the instruction having encountered a hazard and unable to progress through the compute pipeline; store the indication of the instruction in a hazard memory; receive a signal indicating that the hazard has cleared; and cause the instruction to be rescheduled at the beginning of the compute pipeline in response to the signal.
- Hazard management circuitry in a barrel processor is used to handle instructions encountering hazards in the compute pipeline.
- The circuitry stores indications of instructions in a hazard memory when they cannot progress due to hazards.
- When a signal indicates that the hazard has cleared, the circuitry reschedules the instruction at the beginning of the compute pipeline.
- This process helps in managing hazards efficiently in the barrel processor.
Potential Applications
- High-performance computing systems
- Data centers
- Embedded systems
Problems Solved
- Efficient management of hazards in a compute pipeline
- Ensuring smooth execution of instructions in a barrel processor
Benefits
- Improved performance of the barrel processor
- Enhanced reliability in handling hazards
- Better utilization of compute resources
