Traffic, latency, and time series traffic in FPGA design: The data bit that can be transmitted in each clock cycle. Time delay: the clock period that data goes through from input to output. time sequence: The maximum latency between two components. It determines the maximum clock speed of the system. 1 pipeline can increase the traffic, for example, computing x ^ 3, Iterative StructurePipeline: Traffic = 8/1 latency = 3 Time Series = multiplier latenc

[Serialization] FPGA OpenGL series instances Registers of Tilde I. Principles Registers are used for storage by computers and other digital systems.CodeOr the logical part of the data. Its main component is the trigger. A trigger can store one binary code. Therefore, the register for storing n binary code requires n triggers.The functions of registers and data latches are the same. The difference is that the latches are level signal control and

[Serialization] FPGA OpenGL series instances Data Selector Based on OpenGL I. Principles Data selection refers to transferring data from multiple channels to the unique public data channel after selection. The logical circuit that enables data selection is called a data selector. It acts as a single-knife, multi-Throw Switch with multiple inputs. Table 1.1 select a data selector truth table II. Implementation In the design file, enterCo

[Serialization] FPGA OpenGL series instances 3-8 Decoder Based on OpenGL I. Principle: Decoding is the inverse process of encoding. Its function is to identify binary codes with specific meanings and convert them into control signals. A logic circuit with decoding function becomes a decoder.The decoder can be divided into two types:CodeConvert to one of the valid signals. This decoder can be called a unique address decoder. It is often used for

It is a hardware description language used for digital system design. It can be used for logic design at various levels, as well as simulation and verification of digital logic systems, timing analysis, and logic synthesis. At present, OpenGL is the most widely used hardware description language. The highest level of learning hardware is to have a circuit in our hearts. For those who are new to FPGA and HDL, the most important thing is to have more

For multi-fan-out problems, it usually refers to the use of one node to drive multiple lower-level logical devices. For triggers with a

Through the analysis system, the hardware design of the system and the construction of the Nios II CPU system in the QSYS system are all wit

features that can be extracted by machines remain unchanged, This is even harder. A graph has a large scale, a small scale, and different angles. Then, find out which part of the graph has a large scale. Recognition of the same book. What is good information, or feature, is the last corner, because there is information change as long as there is slight change, which is easy to identify. In fact, the method of 3D reconstruction of Avatar is to

During this period, I interviewed several companies and found that large companies are focusing on basic issues. There are several other prominent issues here. They are: synchronous clock design, sub-steady state, asynchronous FIFO. It can be said that if these problems are identified, they will at least meet the technical requirements of 1/3. What is the other 2/3, I will not be clear. Some people have made a race risk glitch. However, for systems that adopt the synchronous design method, these

the hold status and separate them. The shape foreground background must be separated. Machine Vision is actually such a process, with many features in the middle, and different combinations are different things. The key is how to extract features. Features have the largest amount of information and need to be stable and not easily influenced by conditions such as light. Can match the same image? From this perspective, whether the extracted features are unaffected or not is well recognized

My previous question stopped for a long time because-I went to write a book.ObjectiveI started working in March 2012 and now I'm six years away. For the past six years, I have never known anything about SQL Server, only the simplest C # programmers have started, stepping back from a nameless outsourcing company to the middle of a larger financial institution, with wages rising to nearly four times times the size of a new job. In the process of struggle, I also go a lot of detours, once very depr
