affects the frequency of PCI and other bus. The two concepts of the front-end bus and the outer frequency are confusing, mainly because of the long time before (mainly in the Pentium4) the front-end bus frequency is the same as the outer frequency, so it is often called the front-end bus as the outer frequency, which leads to such misunderstanding. With the development of computer technology, it is found that the frequency of the front-end bus is hig

Part 6: delete all the other options except the following: Power Management Options (ACPI, APM) ---> power management option [] Power Management debug support debugging information support for power management. Do not select this option if you do not want to debug the kernel related to power management. ACPI support ---> Advanced Power Interface Configuration support. If the BiOS supports this option, we recommend that you use this [] button option to register power button-based events, such a

perform certain Optimizations Based on the premise that a given object cannot be changed through another pointer. Now you're probably asking yourself, "Doesn't const already guarantee that? "No, it doesn' t. the qualifier const ensures that a variable cannot be changed through a participant pointer. however, it's still possible to change the variable through a different pointer. for example: Void F (const int * PCI, int * PI;); // is *

. 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. UHCI Full Name Universal host Controller Interface, which is a USB host Controller interfac

, 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

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
