general only ensure that on the same AHB port, reads and writes are
completed in the order they are sent. So, when an AHB master sends a
write request to a memory location and then a read request to the same
memory location, the write is completed first and then the read is
serviced. However, write requests from multiple ports that write to the
same memory location would not go through this check. Article last edited on: 2008-09-09 15:47:51 |
