GT series for high-speed transceiver-this is not my concern;
Although HPS can work independently as an independent component, it can be closely connected through the high-performance arm AMBA axitm bus, and under the control of the program, you can use a dedicated 32-bit port to configure the FPGA architecture by the CPU;
Developed to support the new qsys IDE development environment released by Altera (should be a substitute for early versions of the system's systems ):
At the same time, the e
chip manual and bootloader source code.
Step 2: System transplantation, driver development (nuclear-driven development), I only do Linux, so I also recommend learning embedded Linux systems as a standard system, he is open-source and can obtain a lot of learning materials. the operating system is the core of the entire computer science, and it is not easy to get familiar with kernel. You need to read the Linux source code. There is no shortcut to learning kernel and driver development. You only
Hardware and software analysis of audio input channel for Android bottom-line developmentWe all know that headphone mic is integrated in the always-on kind of four-segment headphone mic plug that is more commonly used on Android devices. However, there will be separate cases, compared with the normal PC -mounted Android System, then this is the case. Therefor
Imagination, the cause of a lot of problems, the actual reason only to see to find! If guessing how a failure occurs, it often fixes problems that are not bugs, wasting time and destroying other places, so don't do that. In the medical field, there are stethoscope, blood test, X-ray, B-Super method. Also in software, the method of observation is to set breakpoints, add debug statements, monitor program values, and check memory and so on.
the form of the wince device.
Then, the upper layer of the controller is the Client layer, which is commonly used in three categories: Mass Storage, rndis, and serial. When the wince device needs to behave in what form, it is converted by the Controller Driver (unmount the old client and load the new client ). The device is called function, so the full names are USB function controller driver and USB function client driver.
In fact, the host end also has the Controller layer, which is not stu

download programmer, before the company used by the PC on the download software provided by the manufacturer through the serial port to download, but can not meet the installation site upgrade maintenance needs. Through monitoring and control to obtain the communication command code and format, after the program to download the programmer can work, but always perform the download after a period of time, th
The software and hardware design of an embedded Linux platform-general Linux technology-Linux programming and kernel information. The following is a detailed description.
1. uClinux
Linux is a popular UNIX-like operating system. It is free and open source code and is widely used in personal computers and servers. More importantly, Linux adopts modular design and can be customized in practical applications
Motherboard is one of the basic parts of the computer, especially a bridge, shouldering the CPU, memory, hard disk, graphics and other equipment connection, its performance is directly related to the stable operation of the whole PC computer. In the daily life, we encountered the failure of the motherboard is not uncommon, common motherboard failures are generally the following: first, after the power of the battery can not be self-test, the computer
, exponent is the digit (single-precision 8-bit, double-precision 11-bit), fraction is a valid bit (single-precision 23-bit, double-precision 52-bit).This is not quite like the scientific notation that we usually use.But this approach poses a problem, that is, when the effective bit exceeds a certain time, there will be a precision problem.// true // falseYes, it's equal.Because the first two will be stored as 1.000 ... (52 x 0) x2539007199254740994 will be saved as 1.000 ... 0001x253.The effect
