The Blackfin has a 32 x 32 integer multiply that requires 5 cycles. The UG states that this minics a "C" 32 x 32 integer multiply. Is this the low 32 bits of the 64 bit result? If so then is this not able to do signed fractional fixed point 32 x 32 multiplies? Thanks C&S Audio Labs

Just curious... as far as I can tell, with Analog's current promotion (http://www.analog.com/en/embedded-processing-dsp/blackfin/content/blackfin_development_tools_of fer/fca.html) the asking price is still effectively $2k, you just get the USB emulator thrown in for free. Last year they had the exact same bundle for only $1k, which strikes me as much more manageable. Hence I'm curious.

Hi, I was working on implementation of h.264 algorithm on Blackfin a couple of years back. I had used the elegantly made DMA of the processor to move data in and out of the internal memory (specially during de-blocking) and i was competing with the cache in terms of cycles.So I had a chance to experiment with the cache. I had observed very strange phenomenon occuring with the cache...

Hello there, I was wondering if anyone had tried to create a bit-banging version of a UART for the Blackfin 533. I am working on a project where we unforunately need to use 2 UARTs and the blackfin only has one. Since I am not at work right now, I'll try to explain how we have tried to go about it. First of all we have the TX line of a UART device tied to PF7. We start off by checking...
