RS_latch using vhdl, When using static gates as building blocks, the most fundamental latch is the simple SR latch, where S and R stand for set and reset. It can be constructed from a pair of cross-coupled NOR (Not OR) logic gates. The stored bit is present on the output marked Q. Normally, in storage mode, the S and R inputs are both low, and feedback maintains the Q and Q outputs in a constant state, with Q the complement of Q. If S (Set) is pulsed high while R is held low, then the Q output is forced high, and stays high when S returns to low similarly, if R (Reset) is pulsed high while S is held low, then the Q output is forced low, and stays low when R returns to low.

串口通信的概念非常简单，串口按位（bit）发送和接收字节。尽管比按字节（byte）的并行通信慢，但是串口可以在使用一根线发送数据的同时用另一根线接收数据。它很简单并且能够实现远距离通信。比如IEEE488定义并行通行状态时，规定设备线总常不得超过20米，并且任意两个设备间的长度不得超过2米；而对于串口而言，长度可达1200米。典型地，串口用于ASCII码字符的传输。通信使用3根线完成：（1）地线，（2）发送，（3）接收。由于串口通信是异步的，端口能够在一根线上发送数据同时在另一根线上接收数据。其他线用于握手，但是不是必须的。串口通信最重要的参数是波特率、数据位、停止位和奇偶校验。

檔案傳輸協定(FTP)為目前相當普遍與廣泛使用之網路 應用。然而在傳統檔案傳輸協定之設計下，資料 傳輸透過Out-of-Band(OOB)之機制，意即透過控制頻道(control channel)傳輸指令 ，而實際資料 傳輸則另外透過特定之通訊埠以及TCP連 線，進行 傳送。如此一來 可確保資料 傳輸之可靠與穩定性，但另一方面則會造成傳輸率 (throughput)效能低落 。因此，在本計劃中，我們透過使用SCTP協定並利 用多重串 流 (multi-stream)機制，達到以In-Band機制達成Out-of-Band傳輸之相同效果。在本研究之最後亦透過於開放原始碼系統實作並實際量 測，証

To use the MSSP port to communicate with 3-wire devices, the bytes to be output must be aligned such that the LSB of the address is the 8th bit (LSB) of a byte to be output. From there, the bits should fill the byte from right to left consecutively.

Supplemental information for a high-speed serial bus that integrates well with most IEEE standard 32-bit and 64-bit parallel buses is specified. It is intended to extend the usefulness of a low-cost interconnect between external peripherals, IEEE Std 1394-1995. This standard follows the ISO/IEC 13213:1994 Command and Status Register (CSR) architecture.
