Data control apparatus and method |
摘要 |
This present invention introduces a data control apparatus and method for global navigation satellite system (GNSS). The data control apparatus has a serial transport interface for transporting data blocks at a data transfer rate from a data source. A microprocessor executes a program routine for sequentially writing the data blocks into the main memory unit at a data accessing rate. While the bit sizes of the data blocks have been pre-compressed, the decompressor will decompress the data blocks to reduce the transfer time of the data blocks through the serial interface thereby eliminating a speed bottle of the data transfer rate if the data transfer rate is slower than the data accessing rate of the main memory unit. |
