. Considering the direct connection between the CPU and the main memory and the cache, this bus is usually called the CPU bus or the main bus. Other devices are connected to the CPU bus through the VL bus, therefore, the VL bus is called a local bus. It defines a 32-bit data line and can be extended to 64-bit through the expansion slot. It uses a 33 MHz clock frequency and has a maximum transmission rate of 132 Mb/s, which can work with the CPU. It is a high-speed and efficient local bus that su
Write a uhci bar, also miss Intel, as well as the Intel's several female colleagues, long time no contact, how are you?
UHCI was proposed by Intel. I've been away from Intel for over a year, but I've always felt like I'm going back to Intel one day. So I'm going to be a little concerned about Intel. I really miss Intel, though it's not much, but I just graduated. I didn't think much of the money problem.

, which uses the AMD-8131 hypertransport pci-x tunnel+amd-8111 I/O hub chipset, with the largest support for 2 AMD Opteron processor (UPGA 940-pin). Because the Opteron processor consolidates the memory controller, the memory DIMMs on the motherboard are divided into two groups, each of which is controlled by a single processor memory controller. 4.
Two Opteron 246 processors (2GHZ,1MB L2 cache) are configured on the test server, which consolidates th
Do you want to know what Nic you are using in Linux? In Linux, it is easy to find the network card manufacturer. Open a terminal and enter the following command: sudolshw-Cnetwork if the command above cannot be used in sudo, do not use sudo's privileged mode. Its output looks strange but useful. *-Networkdescription: Wirelessinterfaceproduct: BCM

lines, therefore, we come to the conclusion that increasing the number of road lines or the width of the road can increase the traffic.
So: 250 MHz x 8 = 2G, or: 100 MHz x 20 = 2GBut: Obviously, the width of the road is better than that of more lines. The same is true in PCs. Generally, the latter formula is not used. Reducing FSB will greatly affect the performance.
However, FSB is inaccurate on some AMD CPUs, but the theory is the same. It should be noted that most CPU frequencies are locked

to the physical layer, when the data is received, the MAC protocol first to determine the input information and whether there is a transmission error, if there is no error, The control information is sent to the LLC layer. The layer protocol is an Ethernet Mac defined by the IEEE-802.3 Ethernet standard. The latest Mac supports both 10Mbps and 100Mbps speeds of two.The Ethernet Data Link layer actually contains the MAC (media access control) Sublayer and the LLC (Logical link Control) sublayer.
