Benchmarks show how far behind Windows ARM machines are compared to M1 Macs

We already know that the new Macs powered by the M1 chip have impressive performance that beats nearly all current Macs with Intel processors, but what about Windows PCs? PCWorld compared Microsoft’s Surface Pro X with Apple’s new M1 MacBook Air and the results put the Surface tablet far behind the Mac. Although Windows runs… Continue reading Benchmarks show how far behind Windows ARM machines are compared to M1 Macs

The ARM processor (Thumb-2), part 11: Atomic access and barriers

Raymond On the ARM processor, atomic operations are implemented in terms of a load-locked/store-conditional pair of instructions. LDREX Rd, [Rn, #imm8] ; load word from [Rn, #imm8] and acquire exclusively STREX Rd, Rm, [Rn, #imm8] ; store Rm to [Rn, #imm8] if exclusively held ; Rd = 0 on success or 1 on failure ;… Continue reading The ARM processor (Thumb-2), part 11: Atomic access and barriers
