FIFO算法 选择fifo算法后,每点击一次单步执行按钮,都会执行一次singleFifo函数,函数会首先将当前指令的页号取出。(后续会将此头部元素删除) int page = sequence.get(0).getPageAddress(); 如果当前内存里没有这个页,即!memoryPages.contains(page),执行相应的核心算法: //Platform.runLater是为了配合执行到底时,因...

页面置换算法(FIFO、LRU、OPT) 概念: 1.最佳置换算法(OPT)(理想置换算法):从主存中移出永远不再需要的页面;如无这样的页面存在,则选择最长时间不需要访问的页面。于所选择的被淘汰页面将是以后永不使用的,或者是在最长时间内不再被访问的页面,这样可以保证获得最低的缺页率。

Probably this "Set Tear Scanline" is the replacement for this, at a glance it looks that you can setup which scanline will be used for waiting vblank event, so when you send this scanline it will wait for vblank pulse and doing buffers swap to avoid screen tearing. So try to use this...
资产负债信息——存货账目 从资产负债角度,FIFO 盘存方法优越于 LIFO 盘存方法,因为 FIFO 计量的存货所表明 的价值,更加近似地反映了存货的当前成本(即重置成本)。 GAAP 要求,盘存要使用成本或市价孰低法(LCM/the lower-of-cost-or-market valuation basis)。货物的市价即为其重置成本(replacement cost)。 成本...
It's not really specifically a microcontroller problem, but still looks like the most appropriate section.
