performance of about 90 GFLOPS (gigaFLOPS, 1 billion floating point operations per second), or, in PC users' understanding, it is equivalent to a 45 GHz CPU. This parallel processing board uses Ubuntu Linux 12.04 as its operating system. To make it work smoothly, the reference design and driver of the platform are now available. Why would you want a $99 supercomputer? Of course, in addition to being cool, Andreas Olofsson, CEO of Adapteva, also gave you the reason to choose it: Historicall

In the previous article, we have explained the basic concepts and related principles of the I2C bus protocol. I don't know if you have any knowledge. Now we will introduce this application. First, let's see which devices have the I2C bus protocol. I2C bus application At present, many semiconductor integrated circuits have integrated I2C interfaces. Single-Chip Microcomputer with I2C bus protocol interfaces include: CYGNAL C8051F0XX series, Samsung S3C24XX series, PHILIPSP87LPC7XX series, and

Ideally, someone should immediately report the faults-an operator. The system Infigure 1uses a Microchip technology pic16f84µc, which receives its power from a separate DC sour Ce. As usual, the I/O pins in theµc is at a premium, because of the multitude of the other tasks the controller perf

peripheral device can connect to a common bus and logically separated by the device address. Each peripheral on the cctalk bus must have a unique address. The initial protocol operation was standardized in later versions of port 4800 in Port 9600. Low-cost bridging chips can now be obtained from many manufacturers to allow cctalk to run at least 1 Mbit/s at a baud rate through the USB interface. The cctalk protocol stack has been implemented from a very small 512 byte Rom

partition is not assigned a drive letter, and the system partition is not displayed in the Computers folder. When encrypting a drive that has Windows installed (the operating system drive), BitLocker stores its own encryption and decryption key on a hardware device other than the hard disk, so you must have one of the following hardware devices: A Trusted Platform Module (TPM) ( A computer in which many computers have a special microchip that support

I2C (Inter integrated circuit, internal integrated circuit) bus is a very inexpensive and efficient network for interconnecting peripherals in small, embedded systems. The I2C bus is sometimes called IIC, which has a history of more than more than 20 years. The I2C interface and the SPI interface work the same, but the two methods are different. 　　 The I2C bus uses two lines to connect multiple devices in a multiple-branch bus. This bus is bidirectional, low-speed, and synchronized with the publ

simulated load by a repetitive pulse sequence with a pass (on) or a break (off). When the pass is the DC power is added to the load, when the break is the power is disconnected. As long as the bandwidth is sufficient, any analog value can be encoded using PWM. Most of the load (whether inductive or capacitive) requires a modulation frequency higher than 10Hz, usually with a modulation frequency of 1kHz to 200kHz. Many microcontrollers contain a PWM controller inside them. For example, the

　　 The German Football Association warned fans who might go to Germany to watch the 2006 World Cup match to beware of fake tickets and not to buy tickets from non-distributors and scalper. The World Cup tickets are High-tech products, the tickets are implanted microchip, only through legal access to the fans to enter the ticket. The phenomenon of counterfeit tickets has been rampant in recent years, and the German Football Association hopes to preven

2.1 Indent and line feed[Force] uses 4 spaces as an indent level, with no 2 spaces or tab characters allowed.Explanation: Indents between non-HTML tags, such as script or style tags, are indented with the indentation of the script or style label.Example:[Recommended] No more than 120 characters per line.Explain:Too long code is not easy to read and maintain. But considering the particularity of HTML, do not make the hard request.2.2 Naming[Mandatory]

Mandatory configuration file, that is, no individual configuration files are created for all users. In this case, after you modify the configuration file (such as modifying the desktop wallpaper and system attributes), logout and re-login will restore the configuration to the standard configuration file, for more information about mandatory configuration files, see the official Microsoft documentation.
