US Patent 7415530B2, titled "System and methods for accelerated data storage and retrieval," was issued on August 19, 2008, from an application filed on October 26, 2006. The patent is assigned to Realtime Data LLC and lists James J Fallon as the inventor.

Abstract:
The patent describes systems and methods for improving data storage and retrieval speeds using lossless data compression and decompression. A data storage accelerator employs multiple high-speed compression encoders to compress data at a rate equal to or faster than the incoming data stream. This compressed data is then stored in a memory or storage device, even if that device's native storage bandwidth is lower than the original input data stream. Similarly, a data retrieval accelerator uses high-speed decompression decoders to decompress data retrieved from storage, outputting it at a rate faster than the storage device's retrieval rate. The invention can be used in various applications, including disk storage adapters, random access memory operations, display controllers, and input/output controllers, to reduce data storage, retrieval, and transmission times.

Plain-Language Overview of Independent Claims:

• Claim 1 (Method for accelerated data storage and retrieval): This claim describes a process where data is received at a speed faster than a storage device can normally handle. The data is then compressed at a high enough ratio to allow it to be stored continuously despite the storage device's limitations. Later, this compressed data is retrieved from the storage device at its normal access rate, and then decompressed to produce an output data stream that is faster than the retrieval rate from the storage device itself.
• Claim 7 (System for accelerated data storage and retrieval): This claim outlines a system that includes a "data storage accelerator" with a high-speed compressor to compress incoming data faster than a storage device can typically store it. The system also includes the data storage device itself and a "data retrieval accelerator" with a high-speed decompressor to decompress retrieved data, yielding an output data stream that is faster than the data access rate of the storage device.
• Claim 8 (Data storage accelerator): This claim details a device for speeding up data storage. It contains multiple encoders to compress incoming data blocks. A buffer then stores and counts the size of these compressed blocks. A "compression ratio module" calculates how much each block was compressed and compares this to a minimum required compression level. Finally, a "description module" adds a label to the chosen compressed data block, indicating the type of compression used, before it's sent for storage.
• Claim 10 (Data retrieval accelerator): This claim describes a device for speeding up data retrieval. It has an input buffer to receive compressed data blocks from a storage device. A "descriptor extraction module" analyzes these blocks to find a label indicating the type of compression used. A "decoder module" then uses the appropriate decoder (based on the label) to decompress the data. The decompressed data is then held in an output buffer.
• Claim 12 (Method for accelerated video data storage): This claim describes a method for quickly storing video data. It involves receiving a video data stream, converting it to a digital format, processing the digital video, compressing it at a rate faster than a storage device's capacity, and then storing the compressed video.
• Claim 13 (System for accelerated video data storage): This claim outlines a system for accelerated video storage. It includes a multiplexer to select video input, an analog-to-digital converter to digitize analog video, a video processor, a data storage accelerator to compress the digital video faster than a storage device can store it, and the data storage device itself.
• Claim 14 (Method for accelerating display data retrieval): This claim details a method for speeding up how display data is retrieved. It involves receiving a block of digital display data, decompressing it, and then sending the decompressed data to a display memory.
• Claim 15 (System for accelerating display data retrieval): This claim describes a system that includes a data retrieval accelerator to decompress digital display data blocks and a display memory to receive the decompressed data.
• Claim 16 (Method for accelerated storage of analog, parallel digital, and serial data): This claim covers a method for quickly storing different types of data (analog, parallel digital, or serial). It involves receiving a data block of one or more of these types, compressing it with a high-speed compressor, and then outputting the compressed data for storage.
• Claim 17 (System for accelerated storage of analog, parallel digital, and serial data): This claim describes a system with input streams for analog, parallel digital, and serial data, and a data storage accelerator that compresses these data blocks using a high-speed compressor to produce an output stream of compressed data.
• Claim 18 (Method for accelerated retrieval of analog, parallel digital, and serial data): This claim outlines a method for quickly retrieving various data types. It involves receiving a compressed data block, decompressing it with a high-speed decompressor, identifying the type of data (analog, parallel digital, or serial), and then storing the decompressed data in a memory specifically for that data type.
• Claim 19 (System for accelerated retrieval of analog, parallel digital, and serial data): This claim describes a system that includes input streams for compressed data blocks, a data retrieval accelerator to decompress these blocks with a high-speed decompressor, and at least one data memory to store the decompressed data according to its determined type (analog, parallel digital, or serial).
