PCI, pci-x, pci-e differenceOne, PCI busThe PCI bus standard was developed by Pcisig in 1992 and has a history of more than 8 years. Total bandwidth =33mhzx32bit/8=133mb/s for PCI.Second, Pci-x busPci-x is based on a

. For example, there are 90 samples of Class A In the test sample, and 10 samples in class B. Classifier C1 all the test samples are divided into a class, the classifier C2 the Class A 90 samples to 70, Class B 10 samples 5. Then the classification precision of C1 is 90%,C2, and the accuracy is 75%. But obviously C2 is more useful. In addition, the cost of making different mistakes in some classification problems is different (costing sensitive learning). In this way, the default of 0.5 for cate

Machine Learning: ROC curve of classification algorithm performance indicators and performance indicator roc Before introducing the ROC curve, let's talk about the confusion matrix and two formulas, because this is the basis for ROC curve calculation. 1.

Linux PCI/PCI-E Device configuration space Read and modify 1 Preface PCI and PCI Express, is a high-speed bus commonly used by computers. PCI/PCI-E device drivers and operating system cores in the operating system require access

PCI bus specifies the bus transaction that accesses the configuration space, which is called the configuration read/write transaction. Unlike the storage access transactions that use the storage address for access, the idnumber is used for addressing access to the PCI configuration space. The ID of a PCI device consists of the bus number, device number, and funct

The PCI layer and network interface cards, PCI layer and network interface cardGiven the popularity of the PCI bus, on the x86 as well as other ubuntures, we will spend a few pages on it

------------- Auto Configuration -------------------- PCI provides two separate 32-bit or 64-bit address spaces corresponding to the memory and I/O port address spaces of the x86 Processor family. addresses in these address spaces are assigned by software. A third address space, called the PCI configuration space, which uses a fixed addressing scheme, allows software to determine the amount of memory and I
