SELECTIVE PROVISIONING OF SUPPLEMENTARY MICRO-OPERATION CACHE RESOURCES - A simplified explanation of the abstract
This abstract first appeared for US patent application 17846688 titled 'SELECTIVE PROVISIONING OF SUPPLEMENTARY MICRO-OPERATION CACHE RESOURCES
Simplified Explanation
The patent application describes techniques and mechanisms for selectively adjusting the amount of cache resources available for use in a processor. The processor core includes a dedicated cache for micro-operations and a second cache for data or non-decoded instructions. The core also includes circuitry to monitor cache performance characteristics. Based on these characteristics, the circuitry evaluates whether to increase or decrease the size of a pool of caches available for micro-operations. In cases of overutilization of the first cache, the second cache can be added to the pool.
- The patent application proposes a method to dynamically adjust the cache resources available for micro-operations in a processor.
- The processor core includes a dedicated cache for micro-operations and a second cache for data or non-decoded instructions.
- Circuitry is implemented to monitor cache performance characteristics of the core.
- Based on the performance characteristics, the circuitry evaluates whether to increase or decrease the size of the cache pool available for micro-operations.
- In cases where the first cache is overutilized, the second cache can be added to the pool to provide additional resources.
Potential Applications
- This technology can be applied in various processor architectures, including CPUs and microcontrollers.
- It can improve the efficiency and performance of processors by dynamically adjusting cache resources based on workload demands.
- The technique can be particularly useful in systems with varying workloads or in real-time applications where resource allocation needs to be optimized.
Problems Solved
- The technology addresses the challenge of efficiently managing cache resources in processors.
- It provides a mechanism to dynamically adjust cache sizes based on workload demands, improving overall performance.
- By monitoring cache performance characteristics, the system can identify overutilization and allocate additional cache resources as needed.
Benefits
- Improved performance and efficiency by dynamically adjusting cache resources.
- Optimal resource allocation based on workload demands, leading to better utilization of cache resources.
- Increased flexibility in managing cache sizes, allowing for better optimization in different scenarios.
Original Abstract Submitted
Techniques and mechanisms for selectively increasing or decreasing an amount of cache resources which are to be available for use in the provisioning of decoded micro-operations in a processor. In an embodiment, a processor core comprises both a first cache which is dedicated to caching micro-operations, and a second cache which is coupled to receive data, or non-decoded instructions. The core further comprises circuitry to monitor one or more cache performance characteristics of the core. Based on the one or more cache performance characteristics, the circuitry performs an evaluation to determine whether to increase—or alternatively, to decrease—the size of a pool of one or more caches which are to be available to receive micro-operations. In another embodiment, the second cache is added to the pool based on an indication of an overutilization of the first cache.
