Data Encoder Bypassing Internal Memory Cache
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data processing systems, such as graphics processing systems, face inefficiencies in memory transcoding and copying operations due to the need to fetch and process data through slower memory stores, which can lead to increased processing time and energy consumption.
Innovation Solution
Implementing a data encoder that can read and write data directly to and from external memory systems without using internal memory, allowing for streamlined data handling and processing operations that free up processor resources for more intensive tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is fetched from external memory through internal memory cache for processing, then data processing can be performed, but processing time increases and energy consumption rises due to slower memory access
Solution Approach 1:
The patent extracts the data encoder functionality from the traditional processor-cache-memory pipeline and positions it directly at the memory interface. This allows data to be encoded/decoded directly during memory transactions without requiring fetch operations through the internal memory cache, thereby reducing processing time and improving efficiency
2Productivity
If data is fetched from external memory through internal memory cache for processing, then data processing can be performed, but energy consumption increases due to repeated memory access operations
Solution Approach 1:
The data encoder is extracted from the processor core and positioned at the memory interface to handle encoding/decoding operations directly during memory transactions. This eliminates the need for repeated fetch operations through the internal memory cache, significantly reducing energy consumption while maintaining processing efficiency
3Speed
If data is stored in internal memory cache for processing, then data can be accessed quickly, but cache pollution occurs reducing overall system performance
Solution Approach 1:
The patent extracts data encoding/decoding operations from the processor-cache system and places them at the memory interface. This allows data to be directly encoded/decoded during memory transactions without being loaded into the internal memory cache, preventing cache pollution while maintaining fast data access speeds

AI summary
A data processing system includes an external memory system, a processor and an internal memory system. The internal memory system includes an internal memory that stores data for use by the processor when performing data processing operations. The internal memory system also includes a data encoder associated with the internal memory. The data encoder reads data from the external memory system to the data encoder and returns the data to the external memory system from the data encoder, without storing the data in the internal memory.
