believes that not only do they need to be drastic, to promote the formation of new market rules, but they also need to cultivate things silently. For example, although Sun has already competed with the latest processor chip to add it to the world's four-pronged approach, the low-end and mid-end Unix server market continues to see steady advances in its servers based on the Linux IIIi. According to authoritative sources from Sun, using the low-and mid-end servers to use the iSCSI IIIi is not a m

: Genuineintel(*) Any imitators of Intel processor architecture can support cpuid commands, but they cannot claim that their architecture is a real intel architecture. Therefore, this string is a guarantee that the cpuid command and processor Signature Based on it fully comply with the instructions in this document. If the returned string is not "genuineintel", the actual returned string cannot be interpreted according to the description in this document. Figure 1

Sort the information according to arm official and online documents. Let's take a picture of the Architecture first. ARM microprocessor Series ARM microprocessor currently includes the following series, as well as other manufacturers based on the ARM architecture of the processor, in addition In addition to the common features of the ARM architecture, each series of ARM microprocessor has its own characteristics and application fields. -ARM7 Series -Arm9-series -Arm9e Series -Arm10e Series -Arm1

Byte order and size end, byte order size endWhy is there a byte order problem? 1. memory uses 8 bits as an address unit: the early processor address uses 8 bits as a unit (8-bit processor). That is to say, 8 bits of data can be accessed at a time, and then 16 bits are generated, 32-bit or even 64-bit processors, but to be compatible with the oldest 8-bit processors, 8-bit is used as an address unit. 2. more

1. Re-orderIn order to improve performance when executing programs, the compiler and processor often reorder instructions. Reorder Three types:1. Compiler-Optimized reordering. The compiler can rearrange the execution order of the statements without changing the semantics of the single-threaded procedure.2. Command-level parallel reordering. Modern processors use instruction-level parallelism (Instruction-level Parallelism, ILP) to overlap multiple in

CMP can be divided into isomorphic multi-core and heterogeneous multi-core according to the equivalence of computing kernel. The computation kernel is the same, and the status equivalence is called Isomorphic multi-core. The converse is called he

Intel At the hot Chips Conference at Stanford University, an Intel engineer confessed that Intel's first dual-core Pentium D processor was a sloppy design, and the company soon launched the product more to get into the dual-core era before rival AMD. Jonathan Douglas, chief engineer at Intel's digital enterprise, said Intel hastily designed a dual-core Smithfield processor in 2004 after realising that the single core processor was facing development difficulties. Douglas acknowledges that the de

1: Fundamentals of heterogeneous multi-core communication This paper is mainly based on tms320dm814x series Daphne singular multi-core processor. The dm814x integrates Armcortex-a8 core, C674XDSP core, HD video processing subsystem (HDVPSS), and HD video/image coprocessor (HD-VICP2). HDVICP2 is managed by the ARM968 kernel-based video M3 core and can be completed by H. 264, Mpeg_4, MJPEG codec, HDVPSS by VPSS M3 Nuclear Management, with 2 channels of high-definition video capture channel and di

Origin 3000 ccNUMA system has been widely used in many fields and is a very successful system. To optimize the performance of Origin 3000, SGI's IRIX operating system implements CpuMemSets on it. By binding the application to the processor and memory, it gives full play to the advantages of NUMA's local memory access. The Linux community has also implemented CpuMemSets in its NUMA project and has been applied in SGI's Altix 3000 server. 　　 In this paper, we take the SGI ProPack v2.2 as the rese

Two dual-core hyper-threading (Enabled) processors are available on two physical processors, four cores, and eight logical

Leon processor. Moreover, in 1994, Sun also pushed the SPARC V8 architecture into the IEEE Standard (IEEE 1754-1994).Because the SPARC architecture was originally designed for the server domain, its biggest feature is a large register window, a SPARC-compliant processor that needs to implement a universal register from 72 to 640, each with a width of 64bits and a series of register groups, called the Register window.The architecture of this register window, since it is possible to switch betwee

to the CPU processing capability and PCI bus speed constraints, in practical applications, especially in small packets, the gigabit firewall with this structure is far below the Gigabit forwarding speed (the Bidirectional Forwarding rate is generally below 20% when the 64-byte packet length is long), which is difficult to meet the application requirements of the Gigabit backbone network. 　　Two technologies of gigabit firewall To implement a true gigabit firewall, there are basically two technic

In this way, you can solve the problem by knowing the first few letters of the original equivalence class that each number corresponds to.2.

One day, you open the vial of pill a, pour out a pill in your hand, then open another vial, but accidentally po

different hardware implementations, such as the CPU (32 CPUs) mentioned below, because they all have a common feature: the execution process (or thread).In the traditional single-core era, the only way to improve processor performance is to increase the frequency. But limited by the physical process, the frequency can not be infinitely improved (such as thermal problems, etc.). For multicore processors, the amount of space available increases and the

slot. Besides, the bus bandwidth of Memory Controller is limited, so it cannot handle so much data transmission. Therefore, the CPU designers prefer another method: If the 2nd cores need the data, the 1st cores directly send the data content, and the data only needs to be transferred once. So when will the transfer of cache rows occur? The answer is simple: when one core needs to read the dirty cache rows of another core. But how does the former determine that the latter's cache row has been co

the thread scheduling mechanism; Once this operation starts, it runs until the end, without any context switch (switching to another thread).So, atomic operations ensure that multiple threads are worth the accuracy of memory operations! So How does the atomic operation work? the first is the Inter CPU, people familiar with the Assembly know that the inter instruction set has a lock, if a command set is preceded by a lock, then in the multi-core State, a nuclear execution to the front of the l
