BRIDGE, DATA COMPRESSING METHOD THEREOF AND COMPUTER SYSTEM APPLYING THE SAME
First Claim
1. A bridge coupled between an external host and an external storage device, comprising:
- a first interface coupled to the external host for receiving a first data transmitted from the external host;
an encoder coupled to the first interface for compressing the first data by undistorted compression for producing a second data;
a memory device coupled to the encoder for temporally storing the second data produced by the encoder;
a decoder coupled to the memory device for decompressing the second data stored in the memory device for producing a third data, wherein the third data and the first data are substantially the same; and
a second interface coupled between the decoder and the external storage device for outputting the third data transmitted from the decoder to the external storage device.

Abstract
Provided is a bridge coupled between an external host and an external storage device. The bridge includes a first interface, an encoder, a memory device, a decoder and a second interface. The first interface is coupled to the external host and receives a first data from an external host. The encoder is coupled to the first interface and compresses the first data by undistorted compression for producing a second data. The memory device is coupled to the encoder and temporally stores the second data produced by the encoder. The decoder is coupled to the memory device and decompresses the second data stored in the memory device for producing a third data. The third data and the first data are substantially the same. The second interface is coupled between the decoder and the external storage device and outputs the third data transmitted from the decoder to the external storage device.
