Above all, [ 12 : 8 ] harming error correction theory is mentioned in this paper. the edac circuit designed by vhdl can works normally at different frequency of the cpu clock such as 66mhz 50mhz 40mhz 33mhz. the edac function of the circuit can also be disabled by software tool. meanwhile, some basic devices such as and logic, or logic, not logic and some small scale integrated circuits are also integrated in the fpga
本論文闡述了12 , 8漢明碼糾錯設計過程,採用vhdl語言實現糾錯編碼器( edac ) ,本設計能夠適應cpu時鐘信號clk2的不同頻率,如66mhz 、 50mhz 、 40mhz 、 33mhz ,並且能夠通過軟體的控制使fpga的糾錯編碼功能關閉。The viterbi decoder with hard decision designed by the paper, is aimed at ( 3, 1, 9 ) convolutional coding. the data rate is 9. 6kbps. the data rate received by the rake receiver is spreaded by 127 - bit spread sequences, added pilot signals and modulated by qpsk
該課題所設計viterbi譯碼是針對( 3 , 1 , 9 )卷積碼的硬判決譯碼,數據速率為9 . 6kbps ; rake接收機所接收的數據是擴頻因子為127 、加入導頻且經qpsk調制的擴頻信號,使用verilg硬體描述語言在xilinx公司的ise環境下在用現場可編程門陣列( fpga )來實現viterbi譯碼器和rake接=收機的功能。First, an usb high - speed data acquisition card based on the labview platform was designed. conformed to usb 1. 1 protocol, it can support high - speed data transfer up to 12mb / s. the card was characteristic with anolog digit converting with high sample rate of 24ms / s and high - speed counter, belong to this, it can implement as common io
本工作首先設計開發了以圖形化編程語言labview為應用程序開發平臺的usb高速數據採集處理系統,此卡採用usb1 . 1的總線介面協議,每秒傳輸速率達12mb s ,最高采樣率為24msps ,不僅能夠實現對模擬信號的高速採集,一般的輸入輸出( io )功能,而且能夠實現高速的計數功能。
