The exacting technological demands created byincreasing bandwidth requirements have given riseto significant advances in FPGA technology thatenable engineers to successfully incorporate highspeedI/O interfaces in their designs. One aspect ofdesign that plays an increasingly important role isthat of the FPGA package. As the interfaces get fasterand wider, choosing the right package has becomeone of the key considerations for the systemdesigner.

According to CIBC World Markets, Equity Research, theFlat Panel Display (FPD) industry has achieved sufficientcritical mass for its growth to explode. Thus, it can nowattract the right blend of capital investments and R&Dresources to drive technical innovation toward continuousimprovement in view quality, manufacturing efficiency,and system integration. These in turn are sustainingconsumer interest, penetration, revenue growth, and thepotential for increasing long-term profitability for industryparticipants. CIBC believes that three essential conditionsare now converging to drive the market forward

在基于ASIC或FPGA的设计中,设计人员必须认真考虑某些性能标准,他们面临的挑战主要体现在面积、速度和功耗方面。 与ASIC一样,供应商在FPGA设计中也需要应对面积和速度的挑战。随着门数不断增加,FPGA需要更大的面积和尺寸来适应更多的应用,设计工具需要采用更好的算法以便更有效地利用面积。不断演进的FPGA技术也给设计人员带来一系列新的挑战,电源利用率就是其中之一,这对于为手持或便携式设备设计基于FPGA的嵌入式系统来说是急需解决的问题。
