Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies face challenges in efficiently converting data streams between D-PHY and C-PHY protocols, which are commonly used in multimedia processing, due to differences in data encoding and transmission rates.
Innovation Solution
An interface bridging device (IBD) is developed, comprising a first integrated circuit (IC) component, a bridge component, and a second IC component. The IBD processes digital information, converts D-PHY data streams to C-PHY data streams, and vice versa, facilitating seamless communication between devices using different protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data stream conversion between D-PHY and C-PHY protocols is implemented using dedicated custom integrated circuits or ASICs, then conversion efficiency and data rate are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent implements a universal bridge component capable of converting data streams between multiple protocols (D-PHY to C-PHY and C-PHY to D-PHY) using a single device architecture. This multi-functional approach eliminates the need for separate dedicated conversion circuits for each protocol direction, reducing overall device complexity while maintaining high conversion efficiency through standardized conversion logic and shared resources.
2Adaptability or versatility
If protocol conversion is performed using programmable semiconductor devices, then adaptability and ease of operation are improved, but processing speed and data rate decrease
Solution Approach 1:
The patent employs a hybrid architecture where the bridge component uses programmable logic for protocol adaptation while incorporating hardened IP cores for high-speed serialization/deserialization and encoding/decoding operations. This dynamic configuration allows the device to be programmed for different protocol versions while maintaining high processing speeds through dedicated hardware acceleration for time-critical functions.
Solution Approach 2:
The conversion process is segmented into distinct functional blocks: D-PHY interface layer, conversion logic layer, and C-PHY interface layer. Each layer handles specific tasks independently, allowing parallel processing of multiple data streams and enabling the programmable portion to focus on protocol adaptation while dedicated hardware handles high-speed data transformation, thus maintaining both adaptability and speed.
3Use of energy by moving object
If C-PHY protocol is used for multimedia processing, then power consumption is reduced and data rate is increased, but compatibility with existing D-PHY devices decreases
Solution Approach 1:
The bridge component serves as an intermediary device between C-PHY and D-PHY protocols, allowing C-PHY devices to communicate with legacy D-PHY devices without requiring modification of either endpoint. The bridge translates C-PHY's efficient encoding and signaling into D-PHY compatible formats, enabling existing D-PHY devices to interoperate with new C-PHY devices and maintaining backward compatibility while allowing systems to benefit from C-PHY's lower power consumption and higher data rates.

AI summary
An interface bridging device (“IBD”) capable of facilitating data conversion between data streams of D physical layer (“D-PHY”) and data streams of C physical layer (“C-PHY”) is disclosed. IBD includes a first integrated circuit (“IC”) component, a bridge component, and a second IC component. The first IC component is able to process digital information and is configured to generate a first data stream formatted in D-PHY data stream. The bridge component receives the first data via a D-PHY bus and subsequently converts the first data steam to a second data steam formatted in a C-PHY data stream. The second IC component is configured to obtain the second data stream via a C-PHY bus.
