使用環境:NC-Verilog 5.4 + Debussy 5.4 v9 + Quartus II 7.2 很 多介面都採用serial傳輸,如I2C、LVDS、mini-LVDS…等,在寫入時必須將parallel資料轉成serial,讀出時又得將 serial轉成parallel,所以是個常用的電路,其原理就是使用shift register來達成,本文將一一討論parallel轉serial,serial轉parallel,也順便討論pa...
I have developed the code for QPSK modulation but I am unable to use "reshape " command to perform serial to parallel conversion. I have used reshape with BPSK but it is giving error for QPSK. If anybody can please explain me how to perform the serial to parallel conversion for QPSK-...
Multi Carrier Direct Sequence Code Division Multiple Access(MC DS CDMA) technique is the future generation mobile communication system and to access technology in future advances. Serial and Parallel concatenated codes are used for correcting the errors in data transmission. We proposed hybrid concatenate...
The shift register parallel loads the byte to send (d[7:0]) into the shift register and then shifts out this data on sdo while it shifts in data transmitted from the controller (t[7:0]) on sdi. A counter, cnt, keeps track of how many bits have been sent/received. When sck is ...
(USB), serial AT attachment (SATA), and double-data rate (DDR) interfaces. In some designs, multiple serial communication circuits may be utilized in parallel to further increase data transfer speeds by sending one bit of a data word (referred to herein as a data symbol) via each serial ...
<div p-id="p-0001">A serial peripheral interface (SPI) system including a bus adapter is disclosed. The bus adapter may include a data converter that may be adapted to receive respective first and sec
The converter consists of three blocks: the UART interface, the UART -to SPI interfacing block and the SPI Master interface. The Interface of UART - SPI in SOC will prove very effective in many applications. The communication in the SOC architecture makes easy as they have been connected with...
