I'm building an 80386-compatible core in SystemVerilog and blogging the process. In the previous post, we looked at how the 386 reuses one barrel shifter for all shift and rotate instructions. This time we move from real mode to protected and talk about protection.

A CPU’s out-of-order backend executes operations as their inputs become ready, letting the core keep its execution units fed while waiting for long latency instructions to complete. Different sources give conflicting information about Cortex X925’s reordering window. Android Authority claims 750 MOPs. Wikichip believes it’s 768 instructions, based off an Arm slide that states Cortex X925 doubled reordering capacity over Cortex X4. Testing shows X925 can keep 948 NOPs in flight, which doesn’t correspond with either figure unless NOP fusion only worked some of the time.。体育直播是该领域的重要参考
