Circular Queue Configuration for Host Memory Command Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current host systems face bottlenecks in processing times due to limited capacity in registers for command storage and concurrent command entry, leading to delays and reduced performance when multiple cores attempt to communicate with memory systems.
Innovation Solution
Implementing multiple circular queues across multiple cores, allowing each core to concurrently enter commands and receive responses, dynamically configuring the number of queues based on parameters such as command size and processing power.

Engineering Contradiction Analysis
1Quantity of substance
If multiple cores attempt to concurrently enter commands into a limited-capacity register, then command storage capacity is insufficient, but processing time increases due to bottlenecks
Solution Approach 1:
The patent divides the single register into multiple circular queues, each capable of storing commands independently. This segmentation allows multiple cores to concurrently enter commands into different queues without conflicting for the same storage space, thereby increasing overall command storage capacity and eliminating the bottleneck that caused processing delays
Solution Approach 2:
The patent transitions from a one-dimensional register structure to a multi-dimensional queue system where commands can be organized across multiple queues with different priorities or purposes. This dimensional expansion allows parallel command entry from multiple cores while maintaining organized access patterns
2Productivity
If a single register is used for command storage, then device complexity is low, but productivity decreases due to concurrent access bottlenecks
Solution Approach 1:
By segmenting the register into multiple circular queues, the system enables parallel command processing across different queues, significantly increasing throughput. The segmentation is implemented with clear access rules for each queue, allowing multiple cores to operate concurrently without complex coordination overhead
Solution Approach 2:
The patent implements dynamic queue configuration where the number and size of queues can be adjusted based on system conditions and requirements. This dynamic adaptability allows the system to optimize productivity for different workloads while managing complexity through flexible rather than rigid structures
Data Source
AI summary
Methods, systems, and devices for queue configuration for host interface are described. An apparatus may include a host system including a first circular queue having a first entry that indicates a first command for a memory system and a location of data associated with the first command. The apparatus may include a controller that may access the first entry of the first circular queue and generate a second command for the memory system based on the data associated with the first command and the first entry. The controller may then transmit the second command to the memory system based on generating the command. The controller may also receive a response from the memory system based on transmitting the command. The controller may remove the first entry from the first circular queue based on receiving the response from the memory system.
