I have to admit that I am everything but an expert in operating
system programming, I am just a control engineer, but I am very
interested in the alpha architecture. In fact, the following made
me think of this port: At the university of Vienna I used a dSpace
board equipped with a TMS320C40 for signal processing and control,
especially I wanted to make sigma delta modulation for audio,
but the board was not performing as I liked, just up to 20kHz
sampling frequency. However, I have been told that dSpace uses
either AlphaAXP or TMS320 processors for their boards which tells
me that an AlphaAXP would be well appropriate for signal processing
even with a full featured operating system on top of the real
time task. The only problem now is that I have to convince the
people of an austrian dealer of AlphaAXP based machines that the
port would really be a good idea. Since I am not an expert, I
rely on the rtl group.
