Compressed Chip-to-Chip RGB Transmission for Lower Bandwidth

Solution Overview

Problem

Digital images require significant memory for storage and transmission, and existing methods do not effectively reduce bandwidth and power consumption during transmission, especially when using conventional RGB signaling lines.

Innovation Solution

Compressing RGB information using techniques like cluster compression and serializing it for transmission over conventional RGB signaling lines, reducing the bandwidth and power consumption by transmitting compressed data through existing RGB signaling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If uncompressed RGB image data is transmitted via conventional RGB signaling lines, then the signaling lines can directly carry color information, but the bandwidth and power consumption are excessive

Engineering Contradiction:

Improvepower consumptionVSAvoiddata compression and serialization complexity

Core Design Contradiction:

Loss of energyVSDevice complexity

Solution Approach 1:

The patent segments the image data transmission process into compression (reducing data volume) and serialization (mapping to signaling lines) stages. The compression circuitry divides the image data into compressed representations, which are then serialized into the RGB signaling lines, allowing conventional lines to carry reduced data volumes efficiently

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent changes the data representation parameters by compressing the image data to reduce its volume and then serializing it into a format compatible with conventional RGB signaling lines. This parameter transformation allows the same physical signaling lines to operate with reduced data rates, lowering power consumption

AI summary

In an example, a device includes compression circuitry and transmit circuitry. In operation, the compression circuitry compresses image data of a first image to provide a first set of values indicating colors in the first image and a second set of values identifying a location of each pixel in the first image and a reference to a value, of the first set of values, corresponding to a color of the pixel; generate, based on the first set of values and the second set of values, first serialized data associated with a first color of a second image, second serialized data associated with a second color of the second image, and third serialized data associated with a third color of the second image. The transmit circuitry is operable to transmit the first, second, and third serialized data via first, second, and third signaling lines, respectively.
