Solution Overview

Problem

Existing parameter setting systems for high-performance computers face challenges in reducing power consumption due to manufacturing variations, temperature changes, and voltage fluctuations, as they primarily rely on the receiving circuit for characteristic adjustment, leading to increased size and power consumption.

Innovation Solution

A parameter setting transmission and reception system that includes a transmitter and receiver connected via a transmission path, where the transmitter adjusts a test pattern-based signal to detect and set parameters, and the receiver adjusts its terminal resistor connection based on error counts to minimize signal errors, thereby optimizing parameter settings and reducing power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If characteristic turning is executed by only a receiving circuit, then the transmitting and receiving system can be simplified, but the size of the receiving circuit increases and power consumption increases

Engineering Contradiction:

Improvesystem complexityVSAvoidpower consumption

Core Design Contradiction:

Device complexityVSUse of energy by stationary object

Solution Approach 1:

The characteristic turning function is segmented between the transmitting circuit and receiving circuit. The transmitting circuit performs preliminary characteristic turning based on manufacturing variations, while the receiving circuit performs terminal adjustment. This segmentation allows each circuit to have a smaller, more specialized design rather than one circuit bearing the full adjustment burden.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The transmitting circuit performs preliminary characteristic turning before signal transmission. By pre-adjusting the transmission signal characteristics based on manufacturing variations, the receiving circuit only needs to perform terminal adjustment, reducing its complexity and power consumption while maintaining overall system performance.
