Front-end synchronization: 10MHz sent when the Ethernet MII data arrives into 4 parallel, and to provide 2.5MHz input clock; reception baseband section in addition to providing data MPDU, also provides a 6.25MHz input clock. Taking into account data, enable and clock phase relationship between the transmission path may be affected by the impact of dislocation occurs, so when access to data and enable all to go through by the clock-triggered D flip-flop, so that they and the clock redefine the phase relationship in order to facilitate subsequent processing. DLL frequency modules: Since the system needs, FPGA clock is more than one work, and some provided by the input, and some must be produced by the local oscillator frequency then obtained by the FPGA. Meanwhile, with the 6.25MHz clock output with the MPDU should be divided by the local clock. Make full use of FPGA resources of the DLL frequency, this can improve the quality of the clock.
Kagermann also said that in 2006 the share of SAP in the global market increased to 24%, an increase of 2.8 percentage points over the previous year. Outlook 2007, SAP is expected to come from software and software related services revenue will grow by 12-14%, while 12% last year. In addition SAP also expects operating margin for 2007 will be 27.3% in 2006, fell to 26-27%. Driven by the high-profit software business, EMC fourth-quarter profit increase. In China, EMC added 400 customers in four key sectors to achieve development. EMC fourth-quarter net profit of 148.3 million U.S. dollars last year rose to 389 million U.S. dollars, earnings per share increased from 6 cents to 18 cents. Revenue from 27.1 billion dollars to 3.22 billion U.S. dollars, an increase of 19%. Excluding one-time profit and loss items, EMCs earnings per share were 17 cents, exceeding analyst consensus estimates of 16 cents. Analysts expected revenue of EMC was 31.7 billion U.S. dollars.
