Consider two processes P1 and P2 where period P1 = 50, processing time t1 = 25 and period P2 = 75, processing time t2 = 30. Can these two peocesses be schedule using rate-monotonic scheduling? Illustrate your answer using a Gantt chart. 請問這一題該怎麼解?題目完全看不懂= = 且 rate-monotonic 在哪一個章節有提到? 麻煩指導~感謝 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 61.57.104.57

不能Schedule, 畫畫看 Gantt chart 大概就知道了

rate-Monotonic的簡單定義就是period越短的優先權越大
