The ArmSoM CM5 is another RK3576 board, this time in a compute module form factor with 8GB of LPDDR5 at $95. Geekbench scores of 326 SC / 1,366 MC are essentially identical to the ROCK 4D, which makes sense given they share the same SoC. The price premium over the ROCK 4D comes down to the compute module form factor, which serves a different purpose. If you need something that slots into a carrier board for a specific deployment, the CM5 fills that role. If you’re after a general-purpose dev board and don’t need the modularity, the ROCK 4D at $60 is likely the better buy. I’ve reviewed ArmSoM’s AIM7 previously and came away impressed with their documentation and approach, so they’re a brand worth keeping an eye on.。新收录的资料是该领域的重要参考
For segments, the job is split between hardware and microcode. When LD_DESCRIPTOR fires its protection test at 5CD, the Test PLA OR's the A-bit (bit 8 of the descriptor high DWORD) into a temporary register called PROTUN. Then the microcode at PROT_TESTS_PASSED takes over and writes the modified value back to the GDT or LDT in memory:。新收录的资料是该领域的重要参考
