#100698 - Don't hurt yourself Responding to: ???'s previous message |
XAPP058 does work (sort of). I know because I did an application based on XAPP058. Don't try to convert this to assembly unless you really want to subject yourself to lots of frustration and wasted time. The C source was written by someone who is used to writing code for a PC. It is horribly inefficient, for example using big signed variables for no good reason. As written it takes forever to program a CPLD. To reduce the time to something reasonable you will first have to clean up the source code mess. To do this you will have to take the time to understand what it's doing. I tried to get Xilinx to revise the sample code, but they don't seem to care.
