共建特色产业,小龙虾分拣中心与智慧大棚陆续投用;探索基层联治,建立矛盾纠纷联防联调等机制……如今,两地打破行政区划界限,建立成渝现代高效特色农业带双昌合作示范园区,在基础设施、产业协同、农文旅融合发展等领域深度合作。江红也当上了园区产业发展专员,“从单打独斗到抱团发展,这条‘共富链’不仅链起了资源,更链住了人心。”
What surprised me was that this entire walk is fully hardware-driven -- no microcode involvement at all. The state machine reads the page directory entry, reads the page table entry, checks permissions, and writes back the Accessed and Dirty bits, all autonomously. Since it's hardware-driven, it runs in parallel with the microcode and needs its own memory bus arbitration -- the paging unit must share the bus with both data accesses from the microcode and prefetch requests from the instruction queue.
