Communication, a word that many associate with modern technology, actually has nothing to do with technology. At its core, communication involves nothing more than the spoken or written word, and symbolic languages like art and music. Technology has become synonymous with communication because technology has historically been the method by which communication to or by the general population takes place.

电子书-RTL Design Style Guide for Verilog HDL540页A FF having a fixed input value is generated from the description in the upper portion of Example 2-21. In this case, ’0’ is output when the reset signal is asynchronously input, and ’1’ is output when the START signal rises. Therefore, the FF data input is fixed at the power supply, since the typical value ’1’ is output following the rise of the START signal. When FF input values are fixed, the fixed inputs become untestable and the fault detection rate drops. When implementIng a scan design and converting to a scan FF, the scan may not be executed properl not be executed properly, so such descriptions , so such descriptions are not are not recommended. recommended.[1] As in the lower part of Example 2-21, be sure to construct a synchronous type of circuit and ensure that the clock signal is input to the clock pin of the FF. Other than the sample shown in Example 2-21, there are situations where for certain control signals, those that had been switched due to the conditions of an external input will no longer need to be switched, leaving only a FF. If logic exists in a lower level and a fixed value is input from an upper level, the input value of the FF may also end up being fixed as the result of optimization with logic synthesis tools. In a situation like this, while perhaps difficult to completely eliminate, the problem should be avoided as much as possible.

Methods The structure of FPGA and requirement of system were considered in the experiment, radix-4 algorithm of DIT and recursive structure were adopted. The group float point arithmetic operation was used in the butterfly and the array multiplier was used to realize multiplication. Results The pipeline pattern was used to ensure the system speed, it made fetching data, calculating twiddle factor, complex multiplication and D
