Packet-Based Timeslicing for Multi-Channel Signal Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional time-sliced logic designs for multi-channel signal processing require large memory to save and reload register states during context switching, making them inefficient, especially for a low number of channels, as they need to hold the states of all channels processed.
Innovation Solution
Employing a packet-based timeslicing approach where the processing core handles an entire data fragment before switching to the next channel, reducing the need to save unused register states and minimizing memory consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cycle-based time-sliced logic is used to process multiple channels, then multi-channel data processing capability is improved, but memory consumption increases significantly due to the need to save and reload register states during context switching
Solution Approach 1:
The patent segments the data processing into discrete packets with explicit boundaries, allowing the processing core to handle each packet independently. This segmentation enables the system to process multiple channels without maintaining complete register states for all channels simultaneously, as each packet is processed in isolation and does not require preservation of intermediate register states across channel switches.
Solution Approach 2:
The patent extracts only the necessary state information that needs to be preserved during context switching, rather than saving all register states. By identifying and extracting only the essential state data required for packet processing continuity, the system significantly reduces memory consumption while maintaining the ability to switch between channels efficiently.
2Adaptability or versatility
If cycle-based time-sliced logic is used with multiple channels, then channel switching capability is improved, but device complexity increases due to the need for context switching mechanisms
Solution Approach 1:
By segmenting data into packets with clear boundaries, the system eliminates the need for complex context switching mechanisms. Each packet is processed independently, and the processing core can switch between channels by simply loading the next packet data, without needing to save and restore register states. This segmentation approach simplifies the overall device architecture while maintaining channel switching capability.
Solution Approach 2:
The packet-based approach allows the processing core to operate autonomously on each packet without requiring external intervention for context switching. The packet structure itself contains all necessary information for processing, eliminating the need for complex state management and context switching logic, thereby reducing device complexity.
3Adaptability or versatility
If cycle-based time-sliced logic is used, then multi-channel processing is enabled, but gate area increases due to the need for large memory structures
Solution Approach 1:
The patent extracts only the minimal necessary memory structures required for packet processing, eliminating the need for large memory structures that would be required to store complete register states for all channels. This extraction of essential state information significantly reduces the gate area while maintaining multi-channel processing capability.
Solution Approach 2:
The packet-based approach uses temporary, disposable data structures for processing each packet, rather than maintaining persistent, large-scale memory structures for all channels simultaneously. This approach reduces the required gate area by using minimal memory only during packet processing, rather than allocating large memory structures that would be needed for continuous state preservation across all channels.

AI summary
Systems and methods for multi-channel signal processing by virtue of packet-based time-slicing with single processing core logic. The processing core logic is configured to receive data streams from the multiple communication channels at a data processing unit, and process data fragments of the data streams in a time-sliced manner. The processing core logic can switch from processing a first data fragment of a first data stream to processing a first data fragment of a second data stream at an end of a time slice, wherein the time slice is determined by a fragment boundary associated with the data fragment of the first data stream.
