Hello, I obtained some VHDL code for a round robin arbiter. It was originally written by WD Peterson of Silicore in 2001. It is available (along with other code) from an archive posted in this forum at: http://www.opencores.org/forums/cores/2005/11/001876 I am a bit confused as to what the LASMAS state machine is doing. What is the function of the "EDGE" signal? If anyone can explain the process called "LASMAS_STATE_MACHINE", it would be much appreciated. Alternatively, if anyone knows how to get in touch with the original author, that would be helpful as well (the silicore.net domain doesn't seem to work anymore, so his email with that company is probably not working). Thanks. Sean
