Is there a better way to implement IIR filter?490 (8/7/2011 3:56:41 PM) comp.dsp Hi, all Currently, I'm working on otpimization of speech processing. Previously, my work focuses on video codec, so I have liittle experience of speech processing. In speech processing, IIR filters ... jogging
why integer division is not available in SSE?107 (12/28/2010 12:39:42 PM) comp.arch Hi, all Recently I have such a situation: there is integer division operation in my program. I intend to use SSE intrinsics to rewrite that part of the program. I haven't used integer division instructions bef... jogging
antialiasing argument in function resize1222 (5/27/2010 2:28:29 AM) comp.soft-sys.matlab Hi, all
I am using the function resize and trace it into the resize.m file.
I find that there is an argument called antialiasing.
I hope to use bilinear method to interpolate the image, but if
questions about x862282 (12/29/2009 7:29:25 AM) comp.arch Hi,all
I have no experience in x86 assembly coding previously, but may need
to optimize code on PC.
So I begin to read the manuals doawloaded from Intel's website.
In the diagram of intel core microarchit... jogging
shift direction using correlation2158 (12/23/2009 11:18:08 AM) comp.soft-sys.matlab In case 1, signal2 should be right shift by 2 to be same as signal1.
In case 2, signal2 should be left shift by 2 to be same as signal1.
For the ease of programming, I expect dshift can have a sign to
shift direction using correlation2252 (12/23/2009 11:16:48 AM) comp.dsp Hi,
I am trying to determine the signal shift by correlation method.
The following is the matlab code:
Signal1 = zeros(1,32);
Signal1(3:13) = 8;
Signal2 = zeros(1,32);
Signal2(1:11) = 8;
different data width?392 (11/20/2007 3:51:16 AM) comp.dsp Hi, all In the BDTI's pocket guide, there is a column, Data Width, which divides DSPs into different groups. For TMS320C64x+, the data width is 8/16 bits. For blackfin, the data width is 16 bits. Registers i... joggingsong(109)
