In recent years, large-scale mergers and acquisitions have occurred in the technology and semiconductor industries, not billions of or $ tens of billions of. Just as Broadcom was ready to swallow Qualcomm at $130 billion (about 862 billion yuan), Mavell announced it would buy a rival Cavium (Kay) at a price of about $6 billion (about 40 billion yuan). Mavell (note distinction is not Marvel Mavel) is an American chip manufacturer, specializing in the

announced arm V8 architecture 100-core processor," said Tom Halfhill, senior analyst at Linley Group. ” In the previous Coremark run, TILE-GX used 71-core test results for 231 Coremarks/mhz.Later this year, Cavium will release its 48 arm 64-bit core ThunderX single-threaded processor, Broadcom will be next year to mass production of 16nm based on ARM multithreading processor, currently Broadcom XLP980 has

MINDER Singh, Chairman of LynuxWorks, believes that in the embedded software industry, Linux will become the focus of the next round of development, and virtualization and security technologies are likely to be integrated.At present, Lynx, a developer of the real-time operating system of LynxOS, successfully escaped the fate of the acquisition. In these acquisitions, Intel acquired Fenghe, cavium networks acquired shares from monavista and RIM to obta

composed of two camps: The x86 multi-core camp consisting of Intel and AMD; the MIPs camp consisting of netlogic (RMI), cavium, telira, arm, IBM and other companies. X86 multi-core platforms generally integrate 1 ~ 2 4-core CPU, single-core processing capacity can reach 2 GHz, with the latest PCI-E bus (directly from the North Bridge exclusive Bus), Io efficiency is greatly improved, however, the processing capability of multiple cores is not linear

Application Analysis of Embedded Linux in network processor-Linux general technology-Linux programming and kernel information. The following is a detailed description. Introduction In the last 24 months, supplier organizations were facing economic downturn, coupled with the emergence of network processors (multi-core processors) by companies such as Intel IXP and IBM Power NP, Raza, Cavium and Xilinx, this gives Linux more control and management capa

I never know what the performance is, and I spent all my experience on it for what I thought was illusory. In the past, hardware under the software could also dominate the world. x86, arm, powerpc, cavium, and rmi appeared one by one and were in close contact with me. This is the wake-up in Beijing region. I tho

Recently, the Linux organization announced the establishment of an open source project Io Visor, which focuses on input/output request tasks for the Linux kernel. The project sounds very esoteric, and in fact the project is very relevant to the Internet. The IO visor can create a topology of the entire network without the use of network hardware.In practical scenarios, IO visor can effectively improve the performance of network components such as virtual switches by increasing the number of comp

Other companies that announced the design of multi-core chip products on the Forum include Freescale Semiconductor companies, as well as mobile phone giants such as Motorola, Sun, and Fujitsu. The two-core chip CODE released by the latter is UltraSPARC IV +. At the same time, a company named Cavium Networks in California published an Octeon anti-virus processor product on the Forum to control spam and Trojan viruses. Dep

Assuming that the main program is still running in the old architecture due to the influence of existing investment and traditional thinking in the form of boards, it is inevitable to interact with the main device. I think, this approach is extremely inappropriate. The traditional large and all-Western Empire-type O
