Always thought float subtraction operation is very simple, is to convert it to __float32_add and __float32_sub These two function calls, and then use software simulation to add and subtract operations. But is it really that simple? Is it still the case when some uncomfortable conditions come into being? Processing of 1.1 VDSP on float addition and subtraction operation Under VDSP, you can easily use: float add(float x, float y) { float r = x + y; return r; } float sub(float x, float y) { floa

(UFRACVALN) two register settings. The settings are as follows: can use the value stored in the baud-rate divisor (UBRDIVN) and divisor fractional value (UFRACVALN) To determine the serial tx/rx clock rate (Baud rate) as: Div_val = Ubrdivn + ufracvaln/16 Or Div_val = (sclk_uart/(bps x 16))-1 Where, the divisor should is from 1 to (216–1). By using UFRACVALN, you can generate the Baud rate more accurately. For example, if the Baud rate are 115200 bps and sclk_uart is, UBRDIVN and Ufracvaln are:

Introduction to Startup Parameters Continue with the Tokyo Tyrant (ttserver) Series-Introduction and installation, we continue to look at the startup parameters and configuration. The Ttserver command can start a database instance. Because the database has implemented the abstract API for Tokyo cabinet, you can specify the configuration type of the database at startup. The supported database types are: Memory Hash Database Memory Tree Database Hash database B + Tree Database, The command

Let's take a look at how the big search engines judge Social networks: Bing: "We do look at the social authority of a user." We look on how many people your follow, how many follow You,and this can add a little weight to a listing in regular search Results. " Bing for people on social networks wh

Arm Embedded systems often encounter multiple serial port application requirements, and arm chip system native UART number is limited, so it is necessary to extend more interfaces through other high-speed bus. In this paper, Toradex based on the NXPI.MX6D/6Q processor Apalis i.mx6d/q arm computer module, the Linux system through the Exar scheme to expand the 8-channel serial port. The Apalis i.mx6d/q module itself can support up to 5 UART serial port outputs. Compatible with high speed tia/eia-2

, there is a major problem with the listener channel. Because the coverage area of wireless devices is limited, if both senders are not covered by each other, but both can send data to one receiver, then they will crash at the receiver without knowing it. To deal with this so-called hidden terminal problem, the Protocol includes RTS and CTS to alleviate this problem. Before sending data, the sender sends a request to send the

, you need to press the switch for three seconds. If you press the button, the highlighted green LED will go off, indicating that it is shutting down. The command "/sbin/shutdown-t2-h now" is executed. When the server is turned off, the yellow LED will flash continuously for indication. When the yellow LED does not flash, you still need to wait 10 seconds to turn off the server power. When all processes are killed, the yellow LED will not flash after the disk is detached. If your server supports

seize the wireless channel while the 802.11g device communicates, this seriously interferes with the communication between 802.11 devices. To solve this problem, the 802.11g protocol adopts the "RTS/CTS" technology. Before sending data, a wireless LAN device must Send an RTS (Request To Send) frame To the Wireless AP To Request wireless resources. If the AP does not communicate with other devices, send a C

allocation (NAV). The NAV value instructs each mobile station the time required for the channel to be idle again. All group data contains a Duration field, and NAV updates the Duration field of each group data transmitted. Therefore, NAV actually represents a virtual carrier detection mechanism. MAC uses a combination of physical detection and Virtual Detection to avoid conflicts. The Protocol described above is called a two-way handshake mechanism. In addition, the MAC protocol also contains f
