full-speed debugging. During the debugging, you can view the various CPU registers, you can also set breakpoints, single-step, full-speed, and other debugging functions. Note: During axd debugging, ARM-JTAG debugging agent software should always be turned on, otherwise axd will prompt that the target device is not found. The 2410 GPF4--GPF7 is connected to four diodes respectively. To control the diode light-off is to control the GPF port, to control

TCP/IP supports a variety of link layer protocols, depending on the hardware used by the network, such as Ethernet, ring-based network, FDDI (Fiber Distributed Data Interface) and RS-232 serial lines, etc.
Ethernet link layer protocol, two serial interface link layer protocols (s l p and P), and the loopback (l o p B a c k) drivers that are included in most implementations

through a so-called interface. The interface provides
Abstract function sets with the same hardware type, such as sending or receiving a datagram.
The interface is identified by name. These names are defined in the kernel, rather than in the device file under the/dev directory.
. For Ethernet interfaces, typical names include eth0 and eth1. Device Interface allocation usually depends on
Configure the device sequence. for example, the first installed Ethernet card will be eth0, and the next one
About two years ago, when Li Shanyou, the editor-in-chief of Sohu website, gave a speech on our website, introducing his own eight-point framework for managing Sohu's editorial team (the network person "Li Eight"). At that time I asked him such a question: "You think this model is so good, then where is his bug?" "Li Shanyou replied:" Is the staff too hard, so sohu someone gave me a nickname, called ' Lu Hua Peanut oil-crush experts '.
Time flies, Li Shanyou is now the video website Cool
regular particle filter is re-sampled from the continuous approximation distribution.
According to normalization before or after the selection step, RPF is divided into post-RPF and pre-RPF.

Based on the standard Sir filter algorithm, Pitt and Shephard propose secondary particle filter. Compared with the standard sequence Importance Sampling (SIR) algorithm, the PSO is also based on the sequence Importance Sampling (SIS) algorithm, but selects different importance

You can use the outputdebugstring function to view the entire process of running the program, even the code segment that requires strict practice.
Search for access violation
When a program tries to write data to memory that does not belong to it, Windows will issue an "access violation (access violation)" error message. All windows programmers have encountered access violation errors when developing applications.
Note
In 16-bit windows, use the term general
The client sends a query request to the server and listens for the socket return, waiting for the server to respond. Typically, blocking mode is suspended until the server response is received and cannot continue sending requests.you can use pipelines to improve this situation. in the case of pipelines, the client can request the server regardless of whether the server has a reply. This makes it possible to issue multiple commands at once. The following is a comparison of the time it takes to s

Chapter 2 _ three purposes of The Link Layer of network protocol: sending and receiving IP datagram for the IP module, sending ARP requests for the ARP module, and receiving ARP responses; sends RARP requests to RARP and receives RARP responses. Ethernet is the main LAN technology used by TCP/IP today. It uses CSMA/CD (Multi-Channel Access for carrier listeners with Punch detection). The speed is 10 Mb/s and the address is 48bit. ARP and RARP are used to map 32-bit IP addresses and 48-bit hardwa
