in the past. Pipeline constraint has reached 100 MHz, but Quartus II can only synthesize 68.35 MHz at the end 』 "Wow !! Even if a line of code has not been changed, fmax has changed from 68.35mhz to 102.44 MHz, which is amazing. "the alias of xiaomegao is called. "Other examples of DE2-70 CD will be handed over to you !!』 "OK !! Without being a senior student 』 Download the complete programDe2_70_nios_12_pipeline_bridge.7z ConclusionBrid

the loading speed is faster, thanks to the effectiveness of its read ahead algorithm, if you enable Quartus II for the second time, you do not need to wait for it. You can use the instant opening statement to describe it because Quartus II has already entered the supercache, windows has its own cache, and I feel that it is not so easy. 2. The input time of the system builder can be improved, especially w

Implementation of image acquisition and Display Based on niosⅱ [Date:] Source: Electronic Technology Application Author: Luo Jun, Wu ksong, Liao Honghua [Font:Large Medium Small] 　 With the development of large-scale integrated circuit design technology, the improvement of manufacturing technology and the increase of the number of logical doors on a single chip, the design of embedded systems becomes increasingly complex.

designed using the megawizard tool of Quartus ⅱ. And the. HEX file. Based on the symmetry and periodicity of the rotation factor, when using ROM to store the rotation factor, you can only store a part of the rotation factor table and query the rotation factor required for each butterfly operation by changing the address.4.4 Control UnitThe control unit is used to coordinate and drive various modules and plays a key role in FFT operations.

included in the current design. How can I return an error ?? Double-click the red error and the system prompts no response, so right-click the error and choose "help: The general meaning is that there is no entity for the set region division ...... We recommend that you delete or recreate the region. After reading it, it's still confusing ...... It should have been a very simple operation. How can this problem occur? First, let's calm down and think about it. Don't panic. To sum up this problem

I. SummaryThe FPGA implementation of the algorithm is combined with dsp_builder, Matlab, Modelsim and Quartus II software.Second, the experimental platformHardware platform: Diy_de2Software platform: quartus ii9.0 + modelsim-altera 6.4a (quartus II 9.0) + dsp_builder9.0 + matlab2010bIii. preparation of the software pla

of the target board to be debugged, compile the corresponding debugging ipcore and other general ipcore to generate an embedded debugging system, download it to FPGA, and implement a general debugger. When using the same hardware system, you can select different debugging ipcore to debug different CPUs, and different ipcore can be easily replaced with each other. This method has advantages in design flexibility, development cost, development cycle, and performance. The specific implementation u

Figure 2.10 select a hello World Template Right-click the hello_world project and chooseBuild Project, Compile this project. After compilation, right-click the hello_world project and selectRun as> niosii hardware, Run this cProgram. If the preceding steps are correct, the following results are displayed.

Experiment one Test experiment content???? The test module is created in Simulink, the signal is generated by the test module, and then transmitted to the FPGA,FPGA readout before the signal is not processed back to Simulink for display. This is to test that the entire hardware is functioning properly in the ring and is familiar with the entire underlying development process.Create a model to create a Development Board information????

Today, I found out how to use the HDL coder. The main steps are as follows: 1.

P2P users, set it by yourself. Extended Life Cycle of SSDThe x300 has already used SSD. In the long run, SSD is still the same as ephemeral SSD, but the number of ephemeral SSD cannot be as complex as that of the hard disk, place memory and Memory on ramdisk to reduce the complexity of SSD storage and prolong the lifetime of SSD storage. ConclusionHow to use a memory is different. If a large amount of memory is spent, the memory is useless. It is also a kind of waste. In addition to some mem
