CXL Device Processor Overhead Reduction via Unified Code
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of smart peripheral devices increases, the processor incurs overhead in programming each device independently, leading to inefficient management and operation.
Innovation Solution
An electronic device with a processor and multiple Compute Express Link (CXL) devices uses a combined program code, where each CXL device receives and stores specific program codes based on its type, allowing them to operate independently and reduce processor overhead through interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the processor programs each smart peripheral device independently, then each device can be configured individually, but the processor overhead increases significantly
Solution Approach 1:
The patent combines multiple device-specific program codes into a single unified program code that can be applied to all CXL devices. This merging approach eliminates the need for the processor to individually program each device, thereby reducing processor overhead while maintaining the ability to configure devices through the unified code structure
Solution Approach 2:
The unified program code is designed to be universally applicable across different types of CXL devices. The code includes device type identification mechanisms that allow each device to selectively execute relevant instructions, providing multi-functionality without requiring device-specific programming for each component
2Reliability
If the processor programs each smart peripheral device independently, then device-specific operations can be optimized, but the time required for programming increases
Solution Approach 1:
By merging multiple programming operations into a single unified program code transmission, the system dramatically reduces the time required to configure devices. The unified code is transmitted once and automatically distributed to all CXL devices, eliminating sequential programming time while preserving optimized device-specific operations through code selection
Solution Approach 2:
The unified program code is prepared in advance with pre-included device-specific instructions. When transmitted, the code is already structured with all necessary device-type-specific operations pre-positioned, eliminating the need for time-consuming on-demand programming and allowing devices to be configured immediately upon receipt
