The shot is 40 billion! Marvell formally announces acquisition of Cavium

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

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

The commonly used processors all have several cores.

RMI superscalar xlp processor (8 cores ): The octeon processor of cavium networks (cn58xx has 16 cores ): In fact, octeon 2 has 32 cores: Well-known communication software providers, such as 6 wind, Windriver, and continuous computing, all support RMI xlp or cavium octeon processors.

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

IO Visor: Another open source project was born

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
