This tutorial is illustrated in detail from the installation of a TV stick to scanning, the use of sniffer tools, and the capture and decryption of GSM traffic packets:As a porter, here will be divided into two or three p
was not fully compliant with the USB3 standard. Finally, I bought a PCIe USB3 interface card, it uses the VL805 chip, the price is about $ $, now I can work normally in USB3 mode. Since Bladerf also uses a FX3 chip, I think it may not match asmedia. Adc/dacThe quantization accuracy of the ADC and DAC is important, and adding a bit can double the accuracy. Therefore, the USRP B100 using the 14-bit DAC is 64 times times better than HACKRF accuracy using the 8-bit DAC. While it is said that a chea

(Personal feeling, and content is irrelevant ...)The so-called RTL, as the name implies that is right to left, is an Arabic, Persian, and other cases from right-to-left reading way. This adaptation is required when developing an app that is intended for overseas users. Starting with the Android 4.2 support for native R

Abstract: * RTL Overview The Runtime Library (RTL) is a very large collection of functions. RTL Unit Sysutils and sysconst units The sysconst Unit defines constant strings that display messages by other RTL units. These strings are declared with the resourcestring keyword and saved in program resources. Some of its fea
From RTL view to Verilog languageOnce heard that a certain Daniel said: "When you learn the FPGA to a realm, you see the hardware description language, will no longer be a simple language, but by a logic door composed of the circuit diagram, once reached this realm, can write code to the extreme!" ”The author is how to hope to achieve this realm AH ~ ~, but this realm to the author's feeling is so illusory.Some time ago I wrote a blog titled "Error-pr

In digital circuit designSource codeInput, synthesis, and implementation are three major stages, and the starting point of circuit simulation is also basically consistent with those stages, simulation can be divided into RTL behavior-level simulation, integrated BackDoor-level functional simulation, and time series simulation based on the applicable design stages. This simulation profile model is not only suitable for FPGA/CPLD design, but also for ic

You can also change the architecture and IP address of fpga rtl or qsys, at this time, what steps should the niosii SBT project perform to reflect the modified hardware architecture? Is it generate BSP? Or should it be BSP editor? Or should I build a project? What is the sort order of the distinct rows
