Processor Bypass Unit for Efficient Result Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During data processing by a processor, the time-consuming caching of processing results in a first-in-first-out queue affects the efficiency of program execution, as both writing and reading these results take a long time.
Innovation Solution
A processor design incorporating an arithmetic and logic unit, a bypass unit, a queue unit, and a multiplexer, where the bypass unit acquires and prioritizes valid processing results, allowing them to be directly output to the register file, thereby reducing caching and improving efficiency by bypassing unnecessary results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If processing results are written into a first in first out queue for caching, then the processing results can be stored and retrieved, but the writing and reading processes consume a long time, affecting program execution efficiency
Solution Approach 1:
The patent extracts the essential valid processing results from the queue and outputs them directly to the register file through a bypass unit, eliminating the need to read all cached results sequentially. This extraction of only the necessary data resolves the contradiction by maintaining storage reliability while dramatically improving retrieval speed and program execution efficiency.
Solution Approach 2:
The bypass unit performs preliminary identification and selection of valid processing results before they are fully processed through the queue. By pre-processing and prioritizing results in advance, the system can quickly output critical data without waiting for sequential queue operations, thus resolving the time-consuming reading process while maintaining reliable storage.
2Reliability
If all processing results are cached in the queue, then no results are lost, but the queue becomes congested and processing speed decreases
Solution Approach 1:
The bypass unit extracts and directly outputs valid processing results from the queue before they can congest the system. By removing essential data early in the process, the queue remains less congested, maintaining both result retention reliability and processing speed.
Solution Approach 2:
Instead of caching and processing all results through the queue, the system applies partial action by selectively handling only the valid processing results that need immediate output. This partial processing approach prevents queue congestion while ensuring no critical results are lost, resolving the contradiction between retention and speed.
3Reliability
If the multiplexer sequentially outputs multiple valid processing results to the register file, then all results are utilized, but the output process takes time
Solution Approach 1:
The bypass unit performs preliminary sorting and prioritization of processing results before they reach the multiplexer. By pre-organizing results in priority order, the multiplexer can efficiently output multiple results without extensive sequential processing, thus reducing output time while ensuring comprehensive utilization of all valid results.
Solution Approach 2:
The bypass unit acts as an intermediary between the queue and the multiplexer, pre-processing and organizing results before they enter the sequential output stage. This intermediary function reduces the burden on the multiplexer, allowing comprehensive result utilization with minimized output time.
