Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If logic devices use volatile memory for configuration, then configuration speed is fast, but power consumption increases and configuration data is lost when power is removed
Solution Approach 1:
The patent applies preliminary action by pre-loading configuration data into nonvolatile memory before it is needed for operation. The configuration data is stored in advance in a persistent state, so when the logic device needs to switch modes or restart, the data is already prepared and can be quickly transferred to volatile memory without requiring reconfiguration from external sources.
Solution Approach 2:
The patent uses nonvolatile memory as an intermediary between permanent storage and the volatile configuration memory. This intermediary layer allows configuration data to be preserved when power is removed, then quickly loaded into volatile memory when needed, resolving the contradiction between power consumption and configuration retention by decoupling these two requirements.
2Adaptability or versatility
If logic devices are designed to perform multiple operation modes, then versatility is improved, but device complexity increases
Solution Approach 1:
The patent implements universality by designing a single logic device architecture that can perform multiple operation modes through configurable logic blocks. Instead of creating separate hardware for each function, the device uses a universal structure that can be programmed to perform different operations by loading different configuration data, thereby achieving multiple functions without proportionally increasing hardware complexity.
Solution Approach 2:
The patent applies parameter changes by modifying the operational parameters of the logic device through configuration data rather than changing the physical hardware structure. By changing configuration parameters stored in nonvolatile memory, the same hardware can adapt to perform different operation modes, reducing the need for complex multi-structure designs.
3Adaptability or versatility
If logic devices allow runtime reconfiguration, then adaptability is improved, but configuration time and control complexity increase
Solution Approach 1:
The patent applies preliminary action by preparing configuration data in nonvolatile memory before runtime reconfiguration is needed. Since the data is already loaded and stored in a persistent state, the actual reconfiguration process at runtime involves only transferring data from nonvolatile to volatile memory and updating control registers, which is much faster than generating or fetching configuration data during runtime.
Solution Approach 2:
The patent implements self-service by enabling the logic device to autonomously perform reconfiguration using its own internal nonvolatile memory and configuration logic. The device can load configuration data from its own nonvolatile storage without requiring external configuration equipment, reducing the time and complexity associated with external reconfiguration processes.

AI summary
A logic device includes: a function block and a configuration block. The function block is configurable to perform operations associated with a plurality of operation modes. The configuration block is configured to configure the function block to perform an operation associated with any one of the plurality of operation modes. The logic device also includes a controller configured to control the configuration block so that the function block is configured to perform the operation.
