Is this a newly defined ETH which follows the AETH on the wire?
Thanks, Håkon
Yes,
Atomic masked Fetch and Add uses first 64 bits to provide the date to add,
and the second 64 bits provide the field boundary:
Swap (or Add) data high [63:32]
Swap (or Add) data low [31:0]
Compare data (or Field boundary) high [63:32]
Compare data (or Field boundary) high [31:0]
Atomic masked Compare and Swap uses:
Swap (or Add) data high [63:32]
Swap (or Add) data low [31:0]
Compare data high [63:32]
Compare data high [31:0]
Swap mask high [63:32]
Swap mask low [31:0]
Compare mask high [63:32]
Compare mask low [31:0]
