processor architecture

At present, embedded multi-core processor has been widely used in the field of embedded devices, but embedded human system software development technology still stay in the traditional single-core mode, and do not give full play to the performance of multi-core processor. Program parallelization optimization At present in the PC platform has certain use, but in the embedded platform is very few, in addition

improve performance and maintain the stability of the IT environment to upgrade to dual cores without disruption to the business. In a highly rack-dense environment, the customer's system performance will be greatly enhanced by porting to the dual core with the same power and infrastructure investment. In the same system footprint, customers will gain a higher level of computing power and performance through the use of dual core processors. Dual-core processors (Dual core

The history of 64-bit computing is quite rich and interesting. Companies such as Cray have started using 64-bit registers in their systems in the 70 's, but the truly pure 64-bit computations didn't really come until the 90 's. The first is the R4000 of MIPS, then the DEC Alpha processor. By the middle of the 90, both Intel and Sun had 64-bit designs. The real turning point for consumers is that AMD released a 64-bit PC

I will upload my new book "Write a processor by myself" (not published yet). Today is the beginning. I try to write an article every Thursday. Introduction In this book, we designed and implemented openmips, a processor compatible with the mips32 instruction set architecture. The openmips processor has two versions:

Recently, many projects have been paying more and more attention to the dual-core technology. although the early dual-core technology was proposed by some server manufacturers, such as IBM and HP, with the universality of technology, dual-core technology is no longer available for high-end devices, for example, dual-core has gradually entered the public's life. first, let's take a look at what dual-core is: Dual core processor ): A dual-core

Program parallelizatio

This chapter is selected from the Intel official documentation and translated by myself. Note that the following English word cache is used. If C is in uppercase, that is, cache, it indicates the term "cache". If C is in lowercase, that is, cache, indicates the verb -- indicates saving data to a high-speed buffer storage. Intel 64 and the IA-32 architecture provide the ability to manage and enhance the execution of multiple processors connec

frequency of 533MHz to the CPU, with DDR memory and a front-end bus bandwidth of up to 4.3gb/seconds. But as processor performance continues to improve, it poses a lot of problems for the system architecture. The "HyperTransport" architecture not only solves the problem, but also improves the bus bandwidth more effectively, such as the Amdopteron

independent software providers who build an ever-growing ecosystem to make efforts to build network applications based on network processors. These application modules provided by independent software providers include the following: · Packet processing algorithms, bridge interfaces, and specific network processors are used to develop network engine tools (package engine code assembler, simulators, and Performance Analyzer) running on the data layer ); · Control and management application uni

realized that it was just a matter of novelty. However, this book, the company, and the author have an inexplicable yearning. After graduation, I borrowed this book from my organization. I don't know why, but I always think that the book has its own "Yan ruyu ". It wasn't until you started to get into touch with the processor design project that was just as open-minded. Let me start with the classic "Computer System

releasing her new processor, that is, the processor's speed will increase by one time per 18 months (the processor speed doubles every months), but the Pentium III processor is no better than Pentium The speed of II is increased by one time, while the Pentium II and Pentium II Xeon processors run at 333mhz~400mhz, Pentium III is only operating in 450mhz~550mhz,

graphics interface, which provides up to 4 times times the graphics bandwidth for high-end systems with discrete graphics. With the support of the system manufacturer, you can also obtain options such as TV tuner, Intel High-definition Audio, personal video and remote control, which support Dolby Digital and 7.1 surround sound, while continuing to enjoy the durability battery usage time advantages of Intel Centrino Mobile technology calculations. Features that can help manufacturers achieve dur

launched a UltraSPARC based on dual-core architecture and PA-RISC chip. Only because these products are based on the UNIX architecture, but also high prices, so there is no large-scale access to pervasive applications. Later in 2004, AMD and Intel unveiled their dual-core plans, and for the first time since 2005, they have been supplying dual-core products. Of course, the two companies have launched dual

1 PrefaceWhat is Apache Nifi? The Nifi website explains the following: "An easy-to-use, robust and reliable data processing and distribution system". In layman's terms, Apache NiFi is an easy-to-use, powerful, and reliable data processing and distribution system designed to support data routing, transformation, and system mediation logic for highly configurable indicators.To be clearer about what Nifi can articulate, the following is a brief introduction to the Nifi

Single-core processor Computer system diagram: The previous chipset consists of two chips, called nanqiao and beiqiao, which are connected through PCI. Later, Intel replaced beiqiao with MCH (memory controller hub) and ICH (I/O controller hub) with nanqiao. The two were connected using DMI (direct media interface. In addition, the master processor is connected to the chipset through the FSB (front side bus

Processor designers always focus on different performance promotion strategies in order to perform as many computations as possible within each clock cycle. Faster frequencies, larger data paths, and different instruction sets improve performance. However, one aspect of performance improvement that is most likely to cause misunderstanding is the impact of hyper-threading on processor performance. Hyper-Thr

: the speed of the front-end bus refers to the speed of data transmission, and the external frequency is the speed of synchronous operation between the CPU and the motherboard. That is to say, a 10 million MHz external frequency refers to a digital pulse signal that oscillates times per second; the 800 MHz Front-End bus refers to the amount of data transmitted per second that the CPU can accept is MHz × 64bit bytes 8byte/bit = Mb/s. In fact, the emergence of the "hypertransport"

Intel released the Xeon E5-2600/1600 series processor in early March, following the famous Tick-Tock strategy. The generation of Xeon E5-2600 series still follows the SandyBridge architecture adopted by single-channel Xeon E3, but because E5 is a product for dual-channel applications, it is named "SandyBridge-EP ". As Intel's main product, Xeon E5-2600/1600 series proce
