Innovation Solution
A Duplicate Write Circuit (DWC) that processes write commands to generate sequences of write cycles for predefined address ranges, offloading the processor to perform other tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the processor issues multiple write cycles for initializing memory or I/O operations, then the initialization task is completed, but the processor execution time increases and power consumption increases
Solution Approach 1:
A duplicate write circuit is introduced as an intermediary between the processor and memory/I/O devices. The circuit receives a single write command from the processor and automatically generates multiple duplicate write cycles to predefined address ranges, eliminating the need for the processor to issue multiple write commands manually.
Solution Approach 2:
The duplicate write circuit performs self-service by automatically generating and executing multiple write cycles without requiring processor intervention. Once triggered by a single write command, the circuit independently handles the duplication and execution of write operations to multiple address ranges, freeing the processor to perform other tasks.
2Reliability
If the processor issues multiple write cycles for initializing memory or I/O operations, then the initialization task is completed, but the power consumption increases
Solution Approach 1:
The duplicate write circuit serves as an intermediary that consolidates multiple write operations into a single processor-initiated command. This reduces the total number of active cycles on the bus and minimizes the energy required for signal transmission and processing across multiple write cycles.
Solution Approach 2:
By enabling the duplicate write circuit to self-service and autonomously generate multiple write cycles, the system reduces overall power consumption. The circuit performs the energy-intensive task of multiple write operations in a optimized manner without requiring the processor to remain active for each individual write cycle.
3Ease of operation
If the processor handles each write operation individually, then precise control is maintained, but the task execution efficiency decreases
Solution Approach 1:
The duplicate write circuit acts as an intelligent intermediary that maintains precise control over write operations while improving efficiency. The circuit is configured with predefined address ranges and automatically executes writes to multiple addresses, ensuring accurate initialization while allowing the processor to maintain high-level control without micromanaging each write cycle.
Solution Approach 2:
The duplicate write circuit performs self-service by automatically generating and executing multiple write cycles based on predefined parameters. This autonomous operation significantly improves task execution efficiency while maintaining control precision through programmable address ranges and write patterns.

AI summary
A computer system includes a processor and a Duplicate Write Circuit (DWC). The DWC is to hold a definition that specifies an address range and a plurality of additional address ranges, and to receive, from the processor, a write command that specifies a write-data and a write-address. When the write-address falls outside the address range, the DWC is to generate a write cycle that writes the write-data to the address. When the write-address falls in the address range, the DWC is to generate (i) the write cycle that writes the write-data to the address, and (ii) a sequence of additional write cycles that write the write-data to corresponding addresses in the additional address ranges.
