results. Of course, we tend to use 0 for resetting, which leads to another misunderstanding. But it is clear that all these can achieve the goal. Why is it so embarrassing for Altera ?? Is it necessary ??? According to my master's explanation, the explanation is as follows: (1) In general, external interruptions will not be achieved at the same time, So bit_clearing seems meaningless. For example, if we capture the button, press the button to ma

operation functions. The typical PLD is composed of "and", "non" array, with "and or" expression to implement any combination logic, so PLD can complete a large number of logical combinations in product and form.The 3rd stage Xilinx and Altera respectively introduced the standard gate array similar to the FPGA and similar to the PAL structure of the extended CPLD, improve the speed of the logic, with the architecture and Logic unit flexible, high int

and a gate circuit is given below to illustrate how the LUT implements the logic function.Example 1-1: A truth table for 4 input and gate circuits using a lut is given.As you can see, the LUT has the same function as the logic circuit. In fact, the LUT has a faster execution speed and a larger scale.Part Two: Programming methodsBecause of the high integration of the LUT-based FPGA, its device density ranges from tens of thousands of gates to tens of millions of gates, it can complete the comple

AbstractWeekly slave is used most of the time, so I usually feel better about slave. If component is deployed, when should the master be established and when should the slave be established ?. IntroductionIn Jay Kraut's Hardware Edge Detection Using an Altera Stratix niosii Development Kit, the following statement breaks through the master and slave.

FPGA composition, working principle, and development process Note: The following description is based on the FPGA chip of the Altera series. It is the first time to learn FPGA. Some of the content is summarized by reference to some documents, and there are still few personal analyses and insights. 1. FPGA Overview FPGA, short for field programmable gate array, is a field programmable gate array. It is a product of further development on the basis of

device lookup table. Logical Functions with more than five input variables can be implemented by multiple Lookup tables through combination or cascade. Most FPGA Devices are implemented based on the SRAM lookup table structure. It features high integration (supporting more than one million logic gates) and strong logic functions. It can implement large-scale Digital System Design and complex algorithm operations. However, configuration data will be lost after power loss, A plug-in is required t

Chapter 5 is finally available-FPGA-based c2mif software design and VGA application I. Overview of the MIF File For a long time, do you want to talk about the design and application of the MIF file? Bingo cannot decide on his own. I have written so many, and I am a little tired. Finally, I bit my teeth and wrote it, because no one has ever written it, so I want to write it. If I don't take the ordinary path, I will open up this road, let the design and application of the MIF file application

Niosii Program How to download to flash After debugging the system, the next task is to solidify the program into nor flash (hereinafter referred to as flash) and enable it to run automatically after power-on. But what should we do? I think everyone will think of using the flash programmer of The NIOS. Yes, it is used. However, flash programmer cannot be used at will. If it is not set correctly, it cannot be used. Let's talk less about follow me. Note: The Flash setting method has a direct r
