VHDL/FPGA/Verilog DDR SDRAM控制器的VHDL源代码
DDR SDRAM控制器的VHDL源代码，含详细设计文档。
The DDR, DCM, and SelectI/O&#8482 features in the Virtex&#8482 -II architecture make it the perfect
choice for implementing a controller of a Double Data Rate (DDR) SDRAM. The Digital Clock
Manager (DCM) provides the required Delay Locked Loop (DLL), Dig ...

We address the problem of predicting a word from previous words in a sample of text. In particular,
we discuss n-gram models based on classes of words. We also discuss several statistical algorithms
for assigning words to classes based on the frequency of their co-occurrence with other words. We

&#1048708 In telecommunication, how do we represent a
set of messages, each with an access
frequency, by a sequence of 0’s and 1’s?
&#1048708 To minimize the transmission and decoding
costs, we may use short strings to represent
more frequently used messages.

This is GPS in matlab calculatePseudoranges finds relative pseudoranges for all satellites
listed in CHANNELLIST at the specified millisecond of the processed
signal. The pseudoranges contain unknown receiver clock offset. It can be
found by the least squares position search procedure.
