In this paper, to develop human movement information collecting system with SD card as storage medium. To establishes the human body and computer's relation. The hardware design of the system with PIC32MX microcontroller and the advantages of data recording using SD card are presented. To acquire 6-channel transducer signal to record SD card through serial peripheral interface were reviewed and analyzed...
In this paper, we studied the block LZSS algorithm and investigated the relationship between the compression ratio of block LZSS and the value of index or length. We found that as the block size increases, the compression ratio becomes better. We also found that the bit of length has little effect on the compression performance, and the bit of index has a significant effect on the compression ratio...
