Hi, matrixanov: Thanks for your reply.
What I really want to know is the audio processing algorithm used for the Sound Card. You know that sound cards used in PC are usually PCI based, but I'm now designing an embedded system which may use no PCI bus. The functionaility of audio signal...
Hi, all: I'm a newbie to audio processing. Does anyone here know about the audio
processing algorithm used for PC (like in the Sound Card for example) ? My current
task is to decode the audio information coming from the internet or local harddisk and then send the decoded bitstream to a...
But high-level language tools often provide unefficient RTL code, please refer to www.fpgajournal.com for the article - "Leading Languages - Is There a Future Beyond RTL"
I want to try NIOSII in my new embedded design. According to Altera's announcement, NIOSII can provide up to 200 DMIPS performance(in coming Stratix2), and we also know that there exist abundant hardware resources inside FPGA devices(Registers, High Speed Buses, IPs, etc.), which will make most...
dcm xilinx low frequency mode
Yeah, 24MHz, Even I am using 24.576MHz clock input, my FSX outputs are sometimes stable, sometimes not.
That's the real story of mine!
If your input can only be 9MHz, I think you can try Altera's PLL...
Can glitches be avoided?
So try to use sync design everywhere(as much as possible) in your project. Most glitches are very 'short' time length so that SETUP/HOLD time requirements cannot be satisfied. Therefore, glitches in sync circuit will be filtered and will harmless to your design.
Which FPGA s/w is good?
3 FPGA IDE s/w:
Xilinx ISE: Mature, Stable, Efficient, Best Online Support
Altera Quartus: Stable, Efficient
Lattice ispLever: Newcomer
