Class-Based Dynamic Memory Slot Allocation System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional memory sub-systems face performance issues due to high CPU overhead and resource allocation inefficiencies, particularly when multiple requestors compete for memory resources, leading to greedy allocation scenarios that can lock up systems or limit performance through static partitioning.
Innovation Solution
Implementing a class-based dynamic memory slot allocation system that uses configurable resource allocation constraints, including minimum and maximum threshold settings for each class, allowing for dynamic adjustment of memory resource allocation to optimize system performance and prevent resource hogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If firmware completely manages memory allocation, then flexibility in resource management is improved, but CPU overhead increases and performance is lost
Solution Approach 1:
The patent introduces a hardware-based slot allocation manager as an intermediary between firmware and memory resources. This manager uses a register bit map and automated algorithms to handle memory slot allocation, freeing CPU from direct management while maintaining flexible firmware control through programmable thresholds and constraints.
Solution Approach 2:
The patent replaces the software-based (firmware/CPU) memory management system with a hardware-based allocation system using dedicated circuits, register bit maps, and automated allocation logic. This substitution reduces CPU overhead while preserving adaptability through configurable parameters.
2Extent of automation
If hardware uses a register bit map for resource allocation, then automation is improved, but system complexity increases
Solution Approach 1:
The patent uses a uniform register bit map structure where each bit represents a memory slot in a standardized format. This homogeneous representation simplifies the allocation logic and makes the system easier to manage despite the automation complexity.
3Reliability
If static partitioning is used to prevent greedy allocation, then system stability is improved, but performance is limited due to inability to adjust dynamically
Solution Approach 1:
The patent implements dynamic memory slot allocation where the slot allocation manager can adjust allocations in real-time based on current system conditions, available memory slots, and programmable constraints. This allows the system to respond to changing workload demands while preventing any single requestor from monopolizing resources through enforced minimum and maximum thresholds.

AI summary
A memory slot allocation request specifying a requested number of memory slots is received from a requestor assigned to a particular class among a plurality of classes. It is determined whether allocation of the requested number of memory slots to the requestor results in satisfaction of resource allocation constraints for the plurality of classes. The resource allocation constraints include a first and second threshold for each class that determine how many memory slots can be allocated to each class. Based on determining that allocation of the requested number of memory slots to the requestor results in satisfaction of the resource allocation constraints, the memory slot allocation request is granted. The granting of the memory slot allocation request includes allocating the requested number of memory slots to the requestor.
