Solution Overview
Problem
Current systems fail to identify and optimize the use of accelerator capabilities present in Dual In-Line Memory Modules (DIMM) and Dynamic Random Access Memory (DRAM) chips, leading to reduced system performance.
Innovation Solution
A method and system for generating memory maps that detect and configure accelerators in DIMMs and DRAM chips, determine accelerator information using Serial Presence Detect (SPD) and Multi-Purpose Register (MPR), and create unique memory maps for each accelerator based on its capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If firmware or BIOS is used to configure memory maps without identifying accelerator capabilities, then the system maintains compatibility with standard memory configurations, but system performance is reduced due to suboptimal utilization of accelerator capabilities
Solution Approach 1:
The patent applies preliminary action by detecting and identifying accelerator capabilities in DIMMs during the memory initialization phase, before the system operates. The BIOS/firmware reads SPD/MPR data structures to pre-configure memory maps that incorporate accelerator information, enabling optimal performance from system startup rather than requiring runtime detection or sacrificing compatibility
2Productivity
If accelerator capabilities are identified and unique memory maps are generated for each accelerator, then system performance and accelerator utilization improve, but the complexity of the memory configuration process increases
Solution Approach 1:
The patent applies segmentation by creating unique, separate memory maps for each accelerator rather than a single unified memory map. Each accelerator receives its own customized memory map based on its specific capabilities detected in the DIMM, allowing independent optimization without complicating the overall system architecture. This modular approach enables complex accelerator configurations to be managed through discrete, manageable memory map segments
Solution Approach 2:
The patent uses SPD (Serial Presence Detect) and MPR (Multi-Purpose Register) data structures as intermediaries to bridge the gap between hardware accelerator capabilities and software memory configuration. These standardized data structures provide a systematic interface that automatically conveys accelerator information from the DIMM to the BIOS/firmware, eliminating the need for complex manual configuration while enabling precise accelerator-aware memory map generation
3Device complexity
If a single unified memory map is used for all memory devices, then the configuration process is simplified, but accelerator capabilities cannot be optimized as individual accelerators require specific memory mappings
Solution Approach 1:
The patent applies dynamics by making the memory map configuration adaptive rather than static. Instead of using a fixed unified memory map for all memory devices, the system dynamically generates customized memory maps based on detected accelerator capabilities. The BIOS/firmware reads accelerator information from SPD/MPR and automatically adjusts memory mappings to match each accelerator's specific requirements, enabling the system to adapt its configuration to the actual hardware present
