UWB Module Offloading Packet Processing to Host Processor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless network devices often burden the host processor with packet processing, leading to reduced computational resources and slowed operations, as existing techniques for offloading functions across bus structures like USB are limited.
Innovation Solution
The implementation of an ultrawideband (UWB) module that offloads packet processing functions across a USB bus, including segmentation and reassembly of packets, and supports the processing of network headers, reducing the computational load on the host processor and enhancing communication speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If packet processing is performed in the host processor, then communication functionality is achieved, but computational resources are depleted and device operation slows down
Solution Approach 1:
The patent extracts packet processing functions from the host processor and relocates them to a dedicated wireless network interface card (NIC). This separation allows the host processor to focus on high-level application tasks while the NIC handles packet processing, thereby maintaining communication functionality while significantly improving overall device operation speed and reducing computational resource depletion.
2Productivity
If packet processing functions are offloaded to another processor, then burden on host processor is reduced, but existing bus structures like DMA are limited in supporting this offloading
Solution Approach 1:
The patent implements a universal packet processing architecture in the NIC that can handle multiple packet formats and protocols through a single integrated processor. This multi-functional design allows the NIC to process various types of network packets efficiently, making the offloading solution adaptable to different communication standards and protocols without requiring separate processing mechanisms for each type.

AI summary
A wireless network arrangement includes a host device in communication with a wireless network module (e.g., an ultrawideband (UWB) module, etc.) through a universal serial bus (USB). A protocol is provided to support communication over the USB between the host and the module. In at least one embodiment, the host is able to offload network packet header processing functions to the wireless network module via the USB.
