Hi, Did a search on the dsp site, and couldn't find an article that matched my issue specifically. I have an in house designed board with a 21065L and the JTAG connector made available. Similar to the eval board. On the 21065L, we have connected a RT49LV4096A flash. We may even go up in size, or another one, but the HW interconnect between the 21065L

I have a rather embarrassing question. I have been able to do division easily using the divq method in assembler in previous DSPs, but I can't figure out how to do it in the 21065L assembler. So far, I have been able to compute by hand the 1/n for a number, then do a multiply in 21065l, but now I have numbers that change, meaning variables ins
