QUALITY OF SERVICE CONTROL SCHEME FOR ACCESS TO MEMORY BY IMAGE SIGNAL PROCESSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240320776 titled 'QUALITY OF SERVICE CONTROL SCHEME FOR ACCESS TO MEMORY BY IMAGE SIGNAL PROCESSOR
The patent application relates to determining and processing latency tolerance values of individual pipeline circuits in an image signal processor to generate a quality of service (QoS) parameter indicating latency tolerance.
- Individual pipeline circuits performing image processing functions generate their own latency tolerance values.
- Latency tolerance values are calculated as the time difference between the sampling time of an operation on pixel data and the latest time the operation should be completed on the same pixel data.
- These individual latency tolerance values help determine the QoS parameter for an image signal processing scheme that involves multiple memory accesses for saving and retrieving pixel data in real-time.
Potential Applications: - Image signal processing systems - Real-time image processing applications - Multimedia devices
Problems Solved: - Managing latency in image processing pipelines - Ensuring real-time processing of pixel data - Improving overall quality of service in image signal processors
Benefits: - Enhanced performance in image processing tasks - Optimized latency management - Improved user experience in multimedia applications
Commercial Applications: Title: "Enhancing Image Signal Processing Performance with Latency Tolerance Values" This technology can be utilized in industries such as: - Entertainment (video editing, gaming) - Security (surveillance systems) - Medical imaging
Questions about Latency Tolerance Values: 1. How do latency tolerance values impact the overall performance of an image signal processor?
Latency tolerance values help optimize the processing of pixel data in real-time, improving the quality of service and performance of the image signal processor.
2. What are the key factors to consider when determining latency tolerance values for individual pipeline circuits?
Factors such as sampling time, operation complexity, and memory access speed play a crucial role in calculating latency tolerance values.
Original Abstract Submitted
embodiments relate to generating a quality of service (qos) parameter indicating latency tolerance of an image signal processor by determining and processing latency tolerance values of its individual pipeline circuits. at least a subset of the pipeline circuits that performs image processing functions generates their individual latency tolerance values. each of the individual latency tolerance value is determined as a difference between a sampling time at which an operation is performed on certain pixel data and a latest time by which the operation should be performed on the same pixel data. the individual latency tolerance values generated in this manner provides a mechanism to determine the qos parameter relevant to an image signal processing scheme that involves access to memory multiple times to save and retrieve intermediate pixel data and process incoming pixel data in a real-time manner.
