CACHE BYPASS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18215117 titled 'CACHE BYPASS

Simplified Explanation

The abstract describes a memory controller for cache bypass in computer systems. The memory controller is connected to a memory device and includes a cache with a cache sequence controller. The controller determines the quantity of a specific type of cache look-up results and if it meets a bypass threshold, it performs a bypass memory operation to directly access the memory device.

• The patent application describes a memory controller for cache bypass in computer systems.
• The memory controller is connected to a memory device.
• The memory controller includes a cache with a cache sequence controller.
• The cache sequence controller determines the quantity of a specific type of cache look-up results.
• If the determined quantity meets a bypass threshold, the memory controller performs a bypass memory operation.
• The bypass memory operation allows direct access to the memory device, bypassing the cache.

Potential Applications

This technology can be applied in various computer systems and devices that utilize memory controllers and caches. Some potential applications include:

• High-performance computing systems
• Data centers and server farms
• Gaming consoles and graphics processing units (GPUs)
• Mobile devices and smartphones
• Embedded systems and Internet of Things (IoT) devices

Problems Solved

The memory controller for cache bypass solves several problems in computer systems, including:

• Cache congestion: By bypassing the cache when the quantity of a specific type of cache look-up results exceeds a threshold, the memory controller prevents cache congestion and improves overall system performance.
• Latency reduction: Directly accessing the memory device through bypass memory operations reduces the latency introduced by cache look-up operations, resulting in faster data retrieval and processing.
• Improved memory utilization: By dynamically determining when to bypass the cache, the memory controller optimizes memory utilization and ensures efficient use of available resources.

Benefits

The use of a memory controller for cache bypass offers several benefits to computer systems and devices:

• Enhanced performance: By bypassing the cache when necessary, the memory controller improves system performance by reducing cache congestion and latency.
• Improved responsiveness: Directly accessing the memory device through bypass memory operations reduces data retrieval and processing times, resulting in improved system responsiveness.
• Efficient resource utilization: The dynamic determination of cache bypass helps optimize memory utilization, ensuring efficient use of available resources and maximizing system efficiency.

Original Abstract Submitted

Systems, apparatuses, and methods related to a memory controller for cache bypass are described. An example memory controller can be coupled to a memory device. The example memory controller can include a cache including a cache sequence controller configured to determine a quantity of a given type of result of cache look-up operations, determine the quantity satisfies a bypass threshold, and cause performance of a bypass memory operation that bypasses the cache and accesses the memory device.
