Can someone tell me if using an AVR32 (Atmel uc) which has a floating point calculation unit and DSP instruction set and running at ~50Mhz for a narrow band 8Kbps sampling rate maybe be feasible or out of reach?

Does anyone know of a way to rate limit ssh connections from an IP address ? We are starting to see more and more brute force attempts to guess simple passwords "/usr/sbin/inetd -wWl -C 10" is nice for slowing down attempts to services launched via inetd. Is there an equiv method for doing this to sshd? Running from inetd has some issues supposedly. ---Mike

...tion which need removing because of their performance, memory usage, or accuracy - but completeness and correctness is my priority to start with. It's running real time at about 100MHz of Athlon, and that's good enough to start with. I'd like to cram it into something a lot smaller like 50MHz of ARM eventually, but that'll involve way more than just brute force optimisation. Anyway, it's GPL (for now) and it can be found at: http://www.pslam.demon.co.uk/specbis-2003-03-20.tar.bz2 Enjoy - any comments are very welcome.

Hello, I'm currently evaluating different codecs to create a list of candidates for my current project. My criteria are simple: - What is the expected highest compression ratio where no noticeable degradation occurs yet? I need something like 1/8th compared with wave data. - Is it possible to access the decoded streams for further processing outside of the codec? If yes, can the data be

>What frequency is the ARM processor? The phone shows ARM720 no freq. I'm going to have to guess around 100 Mhz. I ran the same code on an XSCALE ARM 400 mhz. Toshiba e740. Runs about .33 -> .4x realtime. This is the using the generic fixed point defines. Around 5 times faster than I am seeing with the Orange SPV e100. I am using the 1.1.3 codebase. Thanks for taking the time to
