请问,wrapping burst的具体传输过程是什么样的。
in a wrapping burst the address wraps around to a lower address when a wrap boundary is reached.
The wrap boundary is the size of each transfer in the burst multiplied by the total number of transfers in the burst.
Two restrictions apply to wrapping bursts:
• the start address must be aligned to the size of the transfer
• the length of the burst must be 2, 4, 8, or 16.
以上应该作何理解?这个wrap boundary 和 lower address是什么意思?谢谢各位了! |
