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.

春节,东坝汤家村的马灯表演队最为忙碌。省级非物质文化遗产代表性传承人汤春山,是村里第五代大马灯传承人,近40年来一直致力于传承弘扬这一民间艺术。“马灯是乡亲共同保护好的文化遗产。马灯的传承,少了谁都不行。”他一边为娃娃扮相儿,一边讲解。东坝大马灯表演讲究人马合一。每匹竹马由前马首与后马身共同驾驭,前者戴竹编马头面具,后者屈身紧抓前者腰带,通过“左步起、右步跟”的步伐模拟真马动态,行内有着“演马人要先观真马三日,记其鬃毛颤动频率,再练马步百日,方能人马合一”的说法。
