Interface Controller for Communication Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional interface control systems introduce latencies during high-speed operations, degrading processor performance and reducing data transfer rates due to the processor's need to control communication interfaces directly.
Innovation Solution
A controller is introduced to manage the communication interface, receiving communication requests from the processor and executing instructions at each clock cycle to control data transfer, thereby reducing the processor's involvement and improving data transfer rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the processor directly controls the communication interface, then the communication can be established, but latencies are introduced and processor performance is degraded
Solution Approach 1:
A dedicated interface control circuit is introduced as an intermediary between the processor and the communication interface. This control circuit handles all communication protocol operations, signal timing, and data transfer control, allowing the processor to initiate communications without being involved in the actual data transfer timing operations, thereby eliminating latencies while maintaining reliable communication establishment
2Adaptability or versatility
If the processor controls the communication interface, then communication functions can be performed, but additional processing cycles are required reducing data transfer rate
Solution Approach 1:
The interface control circuit serves as a specialized intermediary that handles all communication protocol operations independently. It contains dedicated logic for protocol implementation, timing control, and data transfer management, enabling high-speed data transfer without consuming processor cycles while maintaining full communication functionality
Solution Approach 2:
The patent replaces the mechanical/software-based processor control sequence with a hardware-based interface control circuit that operates autonomously. This hardware implementation executes communication protocols through dedicated logic circuits rather than processor instruction execution, eliminating the cycle-time overhead and enabling continuous high-speed data transfer

AI summary
A system includes a controller for controlling communication between a first device and a second device connected by way of a communication interface. The controller that is associated with the first device is configured to receive a communication request from a processor of the first device for communicating with the second device. Based on the communication request, the controller is further configured to retrieve a set of instructions from an instruction memory that is associated with the first device. Further, the controller is configured to control the communication interface at each cycle of a clock signal by executing each instruction thus controlling the communication between the first and second devices at each cycle of the clock signal.
