Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing networking applications face challenges in efficiently orchestrating complex processing jobs across multiple processing engines, where the sequence of tasks is critical due to dependencies between sub-jobs, leading to inefficiencies in instruction dispatching and completion tracking.
Innovation Solution
A chained-instruction dispatcher circuit with dedicated hardwired digital logic, comprising multiple queue circuits that follow dispatch and go rules to manage instruction types, ensuring sequential completion and efficient resource reuse by using 'dispatch rules' and 'go signals' to coordinate processing engines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a code-executing processor is used to fetch and execute instructions, then flexibility and adaptability are improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent replaces the mechanical system of a code-executing processor with a hardwired digital logic system. The dispatcher circuit uses dedicated hardware logic paths, queue circuits, and control signals instead of software-based instruction fetching and execution, thereby reducing processing overhead and device complexity while maintaining dispatching flexibility through configurable logic paths.
Solution Approach 2:
The dispatcher circuit is designed to autonomously manage instruction dispatching without requiring an external code-executing processor. The hardwired logic automatically tracks instruction completion status, manages queue circuits, and controls the flow of instructions to processing engines, making the system self-sufficient and reducing overall device complexity.
2Reliability
If multiple processing engines are coordinated sequentially, then processing reliability is improved, but loss of time increases due to waiting for completion
Solution Approach 1:
The patent implements feedback mechanisms where completion status of instructions is continuously monitored and fed back to the dispatcher circuit. Queue circuits track the status of each instruction, and upon completion, automatically trigger the next instruction in the sequence. This feedback-driven approach ensures sequential reliability while minimizing waiting time by immediately initiating subsequent operations upon completion detection.
Solution Approach 2:
The dispatcher circuit prepares and queues multiple instructions in advance before execution begins. By pre-loading the instruction sequence into queue circuits and maintaining ready-state instruction buffers, the system reduces idle waiting time between sequential operations while preserving the required execution order through controlled release mechanisms.
3Measurement precision
If instruction queues are maintained for tracking completion status, then measurement precision is improved, but device complexity increases due to additional circuitry
Solution Approach 1:
The patent merges the functions of instruction storage, completion status tracking, and dispatch control into integrated queue circuits. Rather than separate circuits for each function, the queue structures combine data holding with status bit management and control logic, thereby achieving precise tracking of instruction completion while minimizing the overall device complexity through functional consolidation.
4Productivity
If dedicated hardwired digital logic is used instead of a processor, then productivity is improved by reducing overhead, but ease of manufacture worsens due to complex logic design
Solution Approach 1:
The dispatcher circuit is segmented into modular functional blocks including separate queue circuits for different instruction types, dedicated completion status tracking units, and organized control logic paths. This segmentation allows the complex hardwired logic to be designed, tested, and manufactured in manageable modules, reducing implementation difficulty while maintaining high processing throughput through parallelizable structures.

AI summary
A dispatcher circuit receives sets of instructions from an instructing entity. Instructions of the set of a first type are put into a first queue circuit, instructions of the set of a second type are put into a second queue circuit, and so forth. The first queue circuit dispatches instructions of the first type to one or more processing engines and records when the instructions of the set are completed. When all the instructions of the set of the first type have been completed, then the first queue circuit sends the second queue circuit a go signal, which causes the second queue circuit to dispatch instructions of the second type and to record when they have been completed. This process proceeds from queue circuit to queue circuit. When all the instructions of the set have been completed, then the dispatcher circuit returns an “instructions done” to the original instructing entity.
