Coprocessor Register Renaming - A simplified explanation of the abstract
This abstract first appeared for US patent application 18453010 titled 'Coprocessor Register Renaming
Simplified Explanation
The patent application describes a coprocessor with register renaming. The coprocessor receives instructions from processors and includes an array of processing elements and a result register set. Each processing element has a corresponding storage element in the result register set to store instruction results. The result register set has multiple contexts to store coprocessor states from different processors. When an inactive context is detected, the coprocessor stores instruction results corresponding to an active context within the storage elements of the result register set corresponding to the inactive context.
- The coprocessor receives instructions from processors and has an array of processing elements.
- The result register set stores instruction results generated by the processing elements.
- Each processing element has a corresponding storage element in the result register set.
- The result register set has multiple contexts to store coprocessor states from different processors.
- When an inactive context is detected, the coprocessor stores instruction results corresponding to an active context within the storage elements of the result register set corresponding to the inactive context.
Potential applications of this technology:
- High-performance computing systems
- Graphics processing units (GPUs)
- Artificial intelligence and machine learning accelerators
- Cryptocurrency mining rigs
Problems solved by this technology:
- Efficient execution of coprocessor instructions
- Avoiding conflicts and data dependencies between different processors
- Managing and organizing coprocessor states and instruction results
Benefits of this technology:
- Improved performance and throughput of coprocessor instructions
- Enhanced parallel processing capabilities
- Efficient utilization of processing elements and storage elements
- Simplified management of coprocessor states and instruction results
Original Abstract Submitted
A coprocessor with register renaming is disclosed. An apparatus includes a plurality of processors and a coprocessor respectively configured to execute processor instructions and coprocessor instructions. The coprocessor receives coprocessor instructions from ones of the processors. The coprocessor includes an array of processing elements and a result register set comprising storage elements respectively distributed within the array of processing elements. For a given member of the array of processing elements, a corresponding storage element is configured to store coprocessor instruction results generated by the given member. The result register set implements a plurality of contexts to store respective coprocessor states corresponding to coprocessor instructions received from different processors. Based on a determination that one of the contexts is inactive, the coprocessor is configured to store coprocessor instruction results corresponding to an active context within storage elements of the result register set corresponding to the inactive context.
