Coprocessor Register Renaming - A simplified explanation of the abstract
This abstract first appeared for US patent application 17644016 titled 'Coprocessor Register Renaming
Simplified Explanation
The abstract describes a coprocessor with register renaming, which is a component that executes coprocessor instructions in a computer system. The coprocessor receives instructions from processors and includes an array of processing elements and a result register set. The result register set stores coprocessor instruction results generated by the processing elements and implements multiple contexts to store different coprocessor states. When a context is inactive, the coprocessor stores instruction results corresponding to an active context within the result register set.
- The coprocessor is designed to execute coprocessor instructions in a computer system.
- It includes an array of processing elements and a result register set.
- The processing elements generate coprocessor instruction results, which are stored in the result register set.
- The result register set implements multiple contexts to store different coprocessor states.
- When a context is inactive, the coprocessor stores instruction results corresponding to an active context within the result register set.
Potential Applications
- This coprocessor can be used in various computer systems that require efficient execution of coprocessor instructions.
- It can be applied in high-performance computing systems, where coprocessors are commonly used to accelerate specific tasks.
- The coprocessor can also be utilized in embedded systems or specialized hardware that require coprocessing capabilities.
Problems Solved
- Register renaming allows for efficient execution of coprocessor instructions by eliminating data dependencies and improving parallelism.
- The use of multiple contexts enables the coprocessor to handle instructions from different processors simultaneously, improving overall system performance.
- Storing instruction results within the result register set allows for quick access and retrieval, reducing latency in coprocessor operations.
Benefits
- The coprocessor with register renaming improves the efficiency and performance of coprocessor instructions in a computer system.
- It enables parallel execution of instructions and eliminates data dependencies, leading to faster processing.
- The use of multiple contexts allows for better multitasking and handling of instructions from different processors.
- Storing instruction results within the result register set ensures quick access and retrieval, reducing delays in coprocessor operations.
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.
