The TMS320C54x, TMS320LC54x, and TMS320VC54x fixed-Point, digital signal processor (DSP) families
(hereafter referred to as the ’54x unless otherwise specified) are based on an advanced modified Harvard
architecture that has one program memory bus and three data memory buses. These processors also provide
an arithmetic logic unit (ALU) that has a high degree of parallelism, application-specific hardware logic, on-chip
memory, and additional on-chip peripherals. These DSP families also provide a highly specialized instruction
set, which is the basis of the operational flexibility and speed of these DSPs.
提出了利用精密單點定位(precise Point positioning,PPP)技術(shù)進(jìn)行海嘯預(yù)警的方法,并利用TriP軟件對實測浮標(biāo)數(shù)據(jù)進(jìn)行了處理,將得出的海面高數(shù)據(jù)和海嘯波模型疊加進(jìn)行了模擬分析。仿真結(jié)果表明,利用精密單點定位技術(shù)進(jìn)行海嘯預(yù)警,能夠監(jiān)測判斷海嘯的發(fā)生,并獲得海嘯波到達(dá)海岸的波高和時間,提供一定的預(yù)警信息。
A passive optical network (PON) is a Point-to-multiPoint, fiber to the premises network architecture in which unpowered optical splitters are used to enable a single optical fiber to serve multiple premises, typically 32-128. A PON consists of an Optical Line Termination (OLT) at the service provider s central office and a number of Optical Network Units (ONUs) near end users. A PON configuration reduces the amount of fiber and central office equipment required compared with Point to Point architectures
