# Applied Micro Circuits Corporation

Applied Micro Circuits Corporation (also known as AppliedMicro, AMCC or APM) was a fabless semiconductor company designing network and embedded Power ISA (including a Power ISA license), and server processor ARM (including an ARMv8-A license), optical transport and storage products.

## History

In 2004, AMCC bought assets, IP and engineers concerning the PowerPC 400 microprocessors from IBM for $227 million and began marketing the processors under their own name. The deal also included access to IBM's SoC design methodology and advanced CMOS process technology.
In 2009, AppliedMicro changed their branding from AMCC to AppliedMicro, but still retain the name "Applied Micro Circuits Corporation" officially.
In 2011, AppliedMicro became the first company to implement the ARMv8-A architecture with its X-Gene Platform. In November 2012 at ARM TechCon, AppliedMicro demonstrated advanced web search capabilities and the ability to handle big data workloads in an Apache Hadoop software environment with the X-Gene Platform using FPGA emulation. A silicon implementation of X-Gene was first exhibited publicly in June 2013.
In April 2016, information about the forthcoming X-Gene 3 server chips was made available. The release schedule was for the second half of 2017. The company projected an improved performance, over the X-Gene 2, that with allow it to better compete with servers using the x86-64 architecture.
In November 2016, MACOM Technology Solutions announced that they would purchase AppliedMicro. The acquisition was completed on January 26, 2017. MACOM then sold the processor division to the private equity firm The Carlyle Group during October 2017.

## Memberships

AppliedMicro has a sponsor level membership of Power.org and is one of the original members. AppliedMicro is also executive member (Chairman position) of the Ethernet Alliance. AppliedMicro is also a member of the Open Compute Project.

## Business groups
### Processor products

The Processor Products group designed and marketed embedded microcontrollers as well as server processor, packet and storage processors. It included the network processors of former MMC Networks (acquired October 2000) with IBM PowerPC 4xx series microcontrollers (acquired April 2004).
Since acquiring the IBM PowerPC 400 family (marketed under the 405 and 440 series product names), AppliedMicro further developed the 460 series, which integrates the 440 CPU and multicore Power architecture devices.
In January 2008, the AppliedMicro PowerPC 405EX was awarded Product of the Year 2007, by Electronic Product magazine.
In October 2011, AppliedMicro announced its X-Gene Platform, an ARM 64-bit solution aimed at cloud and enterprise servers.

### Connectivity products group

The Connectivity Products group of AppliedMicro designs, manufacturers and markets physical layer devices, framers/mappers and switch fabric devices.

## Class-action lawsuit

In 2005, the company paid $60 million to settle a class-action lawsuit on behalf of investors against the company, including current and former officers and directors. The suit had charged the company with issuing a series of materially false and misleading statements concerning the company's operations and prospects for Q4 2001 and beyond.
