Programming the Microsoft Windows driver model繁中版
透過Windows驅動程式的權威們專業的協助，學習如何使用簡易的方式來撰寫Windows驅動程式。
Microsoft WDM支援隨插即用（PnP）功能，提供了電源管理能力，並詳述撰寫驅動程式/迷你驅動程式的方法。這本由長時間接觸裝置驅動程式的專家Walter Oney 與Windows核心小組共同合作的書提供了大量很實用的例子、圖表、建議，並一行一行分析範例的程式碼，好讓您能夠清楚了解實際上在撰寫驅動程式時所會發生的問題。另外亦更新了Windows XP及Windows 2000的最新驅動程式技術，又告訴您如何除錯。
The Window Design Method
The basic idea behind the design of linear-phase FIR filters using the window
method is to choose a proper ideal frequency-selective filter [which always has
a noncausal, infinite duration impulse response] and then truncate its impulse
response hd[n] to obtain a linear-phase and causal FIR filter h[n]. To truncate the
impulse response of the ideal filter a time window w[n] is used. Available windows
in Matlab are rectangular [or boxcar in Matlab], bartlett, hamming, hanning
The code performs a number (ITERS) of iterations of the
Bailey s 6-step FFT algorithm (following the ideas in the
CMU Task parallel suite).
1.- Generates an input signal vector (dgen) with size
n=n1xn2 stored in row major order
In this code the size of the input signal
is NN=NxN (n=NN, n1=n2=N)
2.- Transpose (tpose) A to have it stored in column
major order
3.- Perform independent FFTs on the rows (cffts)
4.- Scale each element of the resulting array by a
factor of w[n]**(p*q)
5.- Transpose (tpose) to prepair it for the next step
6.- Perform independent FFTs on the rows (cffts)
7.- Transpose the resulting matrix
The code requires nested Parallelism.
