Top 50 EMS Providers Crack $100 BillionMMI identifies the largest providers in the EMS industry.
Burlington, VT (PRWEB) April 11, 2006 -- Manufacturing Market Insider, a newsletter specializing in the EMS (electronics manufacturing services) industry, has released its annual MMI Top 50 list of the worlds largest EMS providers. Together, these 50 companies accounted for 2005 sales of $109.2 billion. This is the first time that the MMI Top 50 exceeded $100 billion in sales.
Combined sales for Top 50 companies grew by 14.4% in 2005. But this growth was heavily influenced by the estimated results of one company, Taiwans Hon Hai Precision Industry. Without Hon Hai, the remaining 49 providers would have produced an aggregate growth of 3.1%.
You can interpret the data in two ways. In one sense, growth of 14-plus percent for the Top 50 points to a continued increase in the practice of outsourcing. But the groups lackluster growth with Hon Hai excluded shows that 2005 was a disappointing year for some large EMS companies, said John Tuck, editor and publisher of Manufacturing Market Insider.
MMI Top 50 providers were ranked based on 2005 sales in US dollars. In order, the top five were Hon Hai, Flextronics, Sanmina-SCI, Solectron and Celestica. A top-ten ranking required $1.61 billion in revenue. To make the MMI Top 50, EMS providers needed 2005 sales of at least $183 million.
In addition to ranking providers by 2005 sales, MMI Top 50 listings include sales growth, number of employees, number of plants, facility space, space in low-cost regions, number of SMT lines and customer data. This special section was published in the March 2006 edition of MMI.

RF Engines Contracted by Australias Defence Science and Technology Organisation (DSTO)Polyphase filtering designs for FPGA provides performance boost for DSTOs advanced receiver design.
(PRWEB) April 10, 2006 -- RF Engines (RFEL), the experts in signal processing for FPGA, have been awarded a contract by Australias Defence Science and Technology Organisation (DSTO), for the provision of high performance digital filter designs. The designs, which form a key role in an advanced receiver system, build on RFELs existing portfolio of signal processing intellectual property (IP), and deliver high quality filtering of wideband signals in real-time.
RFEL will provide DSTO with two filter designs, each based on frequency domain filtering techniques using the polyphase DFT. The first design will support a continuous complex sample rate of 200 MHz with 512 frequency domain weights, whilst the second design will support complex samples rates over 150 MHz with 4096 weights. The filter shapes are fully reprogrammable, and can be changed whilst the filter is running without loss of data.
Both designs are targeted at the Altera EP1S80 FPGA, a relatively small device for the level of performance being achieved.
We are delighted that DSTO have selected RF Engines signal processing technology for this leading edge development, said John Summers, RF Engines CEO. It is a further example of our system design capabilities, and shows how we are able to provide rapid and cost-effective solutions to the most demanding signal processing challenges.
Frequency Domain Filtering
Frequency domain techniques permit efficient implementation of traditional FIR filter functionality and are based on an analysis stage to convert the incoming signal to the frequency domain, and a synthesis stage to convert back to the time domain. The actual filtering process takes place in the frequency domain where it can be performed very efficiently.
The analysis-synthesis pair is typically implemented with a Fast Fourier Transform (FFT) and an Inverse FFT. However, for this contract, RF Engines will be using the Polyphase DFT, which can be considered as a superior replacement to the FFT since it provides far greater frequency isolation between frequency bins for the same transform length. This feature is particularly useful in a filter design, since it allows efficient implementation of very sharp transition bands, and hence greater filter performance for a given silicon resource budget.
For comparative purposes, the polyphase filter design with 4096 frequency domain weights will provide performance equivalent to a FIR filter with 16K taps. At the sample rates required by DSTO, this is well beyond the scope of a single FPGA implementation if attempted with traditional time domain convolution techniques.
Modelling
This work follows on from an initial study phase, in which RFEL was contracted by DSTO to investigate the feasibility of the filter implementation, and to produce bit true Matlab models of the filters. We find that producing accurate simulation models is a crucial step in our design flow, since it allows customers to test out the design prior to the implementation stage, dramatically reducing any risk, added John Summers.
Defence Science and Technology Organisation
The Defence Science and Technology Organisation (DSTO) is part of Australias Department of Defence. DSTOs role is to ensure the expert, impartial and innovative application of science and technology to the defence of Australia and its national interests.
RF Engines Limited
RF Engines Limited (RFEL) is a UK based designer, providing high specification signal processing solutions for FPGA, and turnkey receiver solutions for the homeland security, defence, communications and instrumentation markets.
