Processor Read Issuing Adaptation for Buffer Overrun Prevention

Solution Overview

Problem

Inefficient use of computing resources due to delays in processing data that requires pre-processing, such as decompression, leading to non-deterministic processing rates and buffer overruns when requesting data from storage.

Innovation Solution

A method and system where a processor identifies data characteristics, such as compression status and processing rate, and adjusts memory request rates based on these characteristics and its buffer size, allowing for optimized data fetching and processing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the processor issues memory requests at a high rate to maximize data fetching efficiency, then the read issuing capability and bandwidth are improved, but buffer overruns occur when data requires pre-processing

Engineering Contradiction:

Improveread issuing capabilityVSAvoidbuffer overrun prevention

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The processor dynamically adjusts its read issuing capability based on real-time conditions. When data requires pre-processing, the processor automatically reduces its read issuing rate to match the processing speed, preventing buffer overruns. This dynamic adaptation allows the system to maintain high productivity when possible while ensuring reliability when pre-processing is needed.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system implements feedback mechanisms where the processor monitors data characteristics and processing status, then adjusts memory request rates accordingly. This closed-loop control ensures that the read issuing capability is optimized based on actual system conditions, resolving the contradiction between maximizing bandwidth and preventing buffer overruns.
