Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate memory device is used for each adaptive equalizer device, then each equalizer can have dedicated firmware storage, but the physical space on the PCB increases and costs increase
Solution Approach 1:
The patent consolidates multiple separate memory devices into a single shared memory device that stores firmware for multiple adaptive equalizer devices. This merging approach reduces the total number of memory devices required, thereby decreasing PCB area while maintaining reliable firmware storage through centralized management by the controller circuit.
Solution Approach 2:
The single memory device is designed to serve multiple functions by storing firmware for multiple different adaptive equalizer devices. The controller circuit manages this universal memory resource, allocating firmware to different equalizers as needed, thus maximizing the utilization of a single memory component across multiple functions.
