Host Memory Slot Allocation for Parallel UFS Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data processing systems experience reduced throughput due to the need to repeatedly allocate and deallocate metadata and data buffer regions for each transfer request, leading to inefficiencies in processing multiple slots simultaneously.
Innovation Solution
Allocating dedicated metadata and data buffer regions during the booting process for each slot, which are used for subsequent transfer requests without deallocation until the host is shut down, allowing for parallel processing across multiple slots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dedicated memory regions are allocated for each slot during booting operation, then parallel communication throughput between host and memory system is improved, but memory resource consumption increases
Solution Approach 1:
The patent applies preliminary action by allocating dedicated memory regions (UTRD and UTBD regions) for each slot during the booting operation before any actual data transfer occurs. This pre-allocation eliminates the need for repeated allocation and deallocation during normal operation, enabling parallel communication across multiple slots simultaneously while improving throughput.
2Adaptability or versatility
If memory regions are allocated and deallocated for each transfer request, then memory management flexibility is improved, but processing time increases
Solution Approach 1:
The patent eliminates repeated allocation and deallocation operations by pre-allocating dedicated memory regions during booting. The host controller maintains these regions throughout operation, allowing immediate processing of transfer requests without time-consuming memory management operations, thus reducing processing time while maintaining flexibility through the command manager.
3Productivity
If multiple slots are processed simultaneously, then system performance is improved, but complexity of memory management increases
Solution Approach 1:
The patent applies segmentation by dividing the memory space into distinct dedicated regions (UTRD and UTBD) for each slot. This segmentation allows parallel processing across multiple slots while simplifying management, as each slot has its own isolated memory regions that can be independently accessed without coordination overhead.

AI summary
A method for operating a data processing system including a host and a memory system coupled to each other through a plurality of slots and using a Universal Flash Storage (UFS) interface, the method includes: allocating, by the host, dedicated memory regions respectively corresponding to the slots during a booting operation of the host; communicating, between the host and the memory system in parallel through the slots based on command packets and address information for data buffer regions, the command packets and the address information being stored in the dedicated memory regions; and deallocating, by the host, the dedicated memory regions during a shutdown of the host.
