be easily identified:DimmThe DRAM chip is packaged in a memory module, which is plugged into the expansion slot of the motherboard. The common packaging is a 168-pin dual-inline memory module (Dual inline memory Module,dimm) that transmits data to the storage controller and from the storage controller in 64-bit blocks. The DIMM is developed in a single inline memory Module,simm, and SIMM transmits data in blocks of 32 bits.RankThe memory controller only allows the CPU to do a set of 64bits of d

Some knowledge of DRAM, first recorded and then sorted out.1. What is memory rank?A memory rank is a set of DRAM chips connected to the same chip select, which be therefore accessed simultaneous Ly. In practice they also share all of the same command and control signals, and only the data pins for each DRAM is Separat E (But the data pins is shared across ranks). the term "rank" was created and defined by JEDEC, the memory industry standards Group. On ANBSP;DDR,NBSP;DDR2, Orddr3memory module, ea

Constructs a parent function, if the weight is indicated by the exponent of X, then: 1 weights of 1 grams can be represented by the function 1+x, (the preceding 1 means 1 grams of weights 0) 1 2 grams of weights can be 1+x2 , 1 3 grams of weights can be 1+x3 , 1 4 grams of weights can be 1+x4 , Then the product of the combination of several weights is expressedas: (1+x) (1+x2) (1+x3) (1+x4) =1+x+x2+2x3+2x4+2x5+2x6+2x7+x8+x9+x10, the

? 2. Do I need to use multiple threads? But we are optimizing the algorithm itself. 3. How can I create a power? It seems that the improved recursive version has already been done. Is there anything to do with X itself? Now that iteration is required and fast, we have to save intermediate results like an improved recursive algorithm (refer to dynamic planning). But what if we save intermediate results? How do we know the intermediate results for a number? It doesn't matter if you think about it.

Introduction 1: I. Basic Principles The CRC Check principle is to add an r-bit binary check code (sequence) after a p-bit binary data sequence to form a binary sequence with a total length of n = p + r; there is a specific relationship between the verification code appended to the data sequence and the content of the data sequence. If one or some bits in the data sequence are wrong due to interference or other reasons, this specific relationship will be damaged. Therefore, you can check the data

verify the data sent this, in the receiver we use the data received by using "mode two division" divided by the use of polynomial, if the remainder of 0 indicates that there is no error in the transmission process, if not 0 indicates that there are errors in the transmission. Step1: Confirm the use of polynomials, usually we will adopt a fixed polynomial, common several kinds of generating polynomials such as: Crc8=x8+x5+x4+x0 Crc-ccitt=x16+x12+x5+x0

using the PCI video card as a last resort. PCI-E interfaces vary based on bus bit width, including X1, X4, X8, and x16, while X2 mode will be used for internal interfaces instead of Slot Mode. The PCI-E specification is connected from one channel to 32 channel connections, with very strong scalability to meet different system equipment for different data transmission bandwidth needs. In addition, the shorter PCI-E card can be inserted into the longer

PCIExpress specifications are connected from one channel to 32 channels, with high scalability. • A shorter PCI Express card can be inserted into a longer PCIExpress slot. The PCI Express interface supports hot plugging. The PCI Express card supports three types of voltages: + 3.3 V, 3.3vaux, and + 12 V. • PCI Express interface bits used to replace th
