CPU is going to be memory access or I/O access.The T1 state is the address state, and the processor issues the address of the memory or I/O port to be accessed. The CPU sends out a high 4-bit address via the address/status line A19/S6~A16/S3, ad15~ad0 the low 16-bit address via the address/data line. Since 8086 of the 20-bit address lines are multiplexed with the state and the data line, the address signal must be locked up in the T1 state. In the T1 state, the address latch of the CPU enables

if multiple hosts are configured, use only the first; get "hosts." Prefix, if there are multiple then use the first, then parse out hostname and port, build a Inetsocketaddress object address; Get connection timeout "Connect-timeout", set ConnectTimeout, If less than 1000 is configured, the default value of 20000 is used, the unit is MS; Gets the corresponding time "Request-timeout", sets the Requesttimeout, if the configured less than 1000, then uses the default value 20000, the unit MS; Gets

realized by using multiple circuits and packet switching connections on a single terminal. You can support business with different quality requirements, such as voice and packet data, and ensure high quality and perfect coverage. (2) High spectrum efficiency. WCDMA can efficiently use the radio spectrum. Since it uses single cell multiplexing, frequency planning is not required. The network capacity can be greatly improved by using the layered cell structure, adaptive antenna array and coherent

network. Although the three-tier network configuration is complex, it can be deployed automatically through the Controller. As long as the port of the network device is connected through a cable, all network configurations are automatically deployed. For example, in a VXLAN network, as long as the network device is configured with a route to connect to the Controller, the interface address is connected, and the Controller automatically sends a VXLAN configuration when it perceives a port UP wit

Press "Enter" button to enter the Raid editing window, in the editing window can set the mode of RAID, it is important to note that many RAID cards for the user-provided mode is used in the storage mode expression, wherein "Stripe" Bar storage is RAID 0 mode; " Mirror "represents RAID 1, while" Mirror/stripe "represents the raid0+1 mode. The user can switch the RAID mode using the SPACEBAR, select "Mirror/stripe" mode, and set the four drive in the channel to "Y" status. After setting is comple

multiple businesses. At the same time, the high-speed programmable hardware FPGA manufactured by the current hardware technology can process 40g data streams of the packet header, thus providing the possibility of multi-service support. Gangwan network Co., Ltd. saw this possibility and found the theoretical basis for building the hardware platform. After three years of painstaking research, at last, ASIC + FPGA + TCAM is implemented to achieve high-

address transformation mechanism, also known as the Fast Table (TLB), which is used to store the page table entries currently accessed. The address transformation mechanism with a fast table is shown in four. Because of the cost of the relationship, the fast table can not be done very large, usually only 16~512 page table items.The above address transformation mechanism is very good for small and medium programs, fast table hit rate is very high, so there will not be much performance loss, but
