一种新型基于双口ram的异步fifo

说明：  电网协议信道解交织器设计FPGA实现，适用于PB16的宽带电力线载波通信(Grid protocol channel deinterleaver design FPGA implementation, suitable for PB16 broadband power line carrier communication)

虽然Loeffler DCT实现了良好的质量转换

这是用于阵列乘法器baugh wooley 。这是写Verilog代码。它表明8位阵列乘法。这是输入含有8,8每输出有15位

一个简单的千兆以太网UDP协议的实现,可以实现数据的收发和ARP，实现PC端与FPGA的以太网通信(A simple implementation of Gigabit Ethernet UDP protocol can realize data sending and receiving and ARP, and realize Ethernet communication between PC and FPGA.)

八位串行乘法器 缺点：乘法功能是正确的，但计算一次乘法需要8个周期，因此可以看出串行乘法器速度比较慢、时延大。 优点：该乘法器所占用的资源是所有类型乘法器中最少的，在低速的信号处理中有广泛的使用。(Eight bit serial multiplierDisadvantages: the multiplication function is correct, but the computation of one multiplication requires 8 cycles, so it can be seen that the serial multiplier is slow and time-consuming. Advantages: the multiplier occupies the smallest number of resources in all types of multipliers, and is widely used in low speed signal processing.)

Floating Point FP multiplication is widely used in large set of scientific and signal processing computation. Multiplication is one of the common arithmetic operations in these computations. A high speed floating point double precision multiplier is implemented on a Virtex 6 FPGA. In addition, the proposed design is compliant with IEEE 754 format and handles over flow, under flow, rounding and various exception conditions. The design achieved the operating frequency of 414.714 MHz with an area of 648 slices.
