COMPUTER ACCELERATING DEVICE USING NOVEL USB PROTOCOL BASED ON MULTI CHANNEL SLC NAND AND DRAM CACHE

摘要

A computer accelerating device using a novel USB protocol based on multi channel SLC NAND and DRAM caches the computer accelerating device comprising a main control chip and an SLC NAND module and having a USB interface for connecting to a computer; the computer accelerating device creates and allocates cache files in SLC NAND and DRAM for a computer caches active system files and application programs and pre reads frequently read or written scattered files to serve as a high speed cache; meanwhile a device drive improves a USB protocol optimizes a BOT protocol in a traditional USB interface protocol and optimizes resource allocation on a USB transport protocol. The algorithm and framework of the device employ the following design: 1. the device virtualizes application programs so as to pre store into the device all program files and the system environment files required by the programs; 2. in multi channel mode an array module integrates a plurality of SLC NAND chips and employs a multi channel main control; 3. identifying data for use of a system by long term monitoring of user habits for and pre storing the data in the device; 4. providing intelligent compression and background automatic release of system memory.
