12.3.1 PL192 VIC timingPL 192 VIC(Vectored Interrupt Controller向量中断控制器) 时序
As its part of the handshake mechanism, the PL192 VIC:作为握手装置的一部分,PL192 VIC:
1. Synchronizes IRQACK on its way in if the peripheral port clocking mode is
asynchronous or bypasses the synchronizers if it is in synchronous mode.如果外围端口的时钟模式是异步的,或者在同步模式中绕过了同步装置,那么VIC应使IRQACK (中断请求确认Interrupt Request Acknowledge,是由处理器发出的信号,用来告诉VIC:我想读取某某中断的中断处理程序的地址 )同步。
2. Asserts IRQADDRV when an address is ready at IRQADDR, and holds that address until IRQACK is sampled LOW, even if higher priority interrupts come along.当IRQADDR(中断处理程序地址)处的地址已准备好,VIC断言 IRQADDRV(中断内存地址请求有效,是由VIC发出的信号,告诉处理器:ISR的地址已经发送,而且有效,放心读吧),并且保持那个地址知道IRQACK抽样值为低电平,即使出现了更高优先级的中断请求。
3. Stacks the priority that corresponds to the vector address present at IRQADDR when it samples the IRQACK signal LOW, while IRQADDRV is HIGH.当采样IRQACK信号低且IRQADDRV高电平时,VIC保存与IRQADDDR处显示的向量地址相关的优先级。
4. Clears IRQADDRV so the processor can recognize another interrupt. If nIRQ is also to be deasserted at this point because there are no higher priority interrupts pending, it is deasserted before or at the same time as IRQADDRV to ensure that the processor does not take the same interrupt again.VIC清除IRQADDRV,处理器可以识别另一个中断请求。如果因在此期间没有更高优先级的中断请求而使nIRQ在该点处于待解除认定状态,它应先于或者与IRQADDRV程序同步被解除认定,以确保处理器不会再次进行中断。
12.3.2 Core timing核心时序
As its part of the handshake mechanism, the core:作为握手装置的一部分,核心:
1. Starts an interrupt entry sequence when it samples the nIRQ signal asserted.在采样被断言的nIRQ信号时,开启一个中断入口序列。
2. Determines if an FIQ or an IRQ is going to be taken. This happens after the interrupt entry sequence is started. If it decides that an IRQ is going to be taken, it starts the VIC port handshake by asserting IRQACK. If it decides that the interrupt is an FIQ, then it does not assert IRQACK and the VIC port handshake is not initiated.决定是否实行快速中断请求FIQ(Fast Interrupt Request,FIQ)还是中断请求IRQ,这发生在实行中断入口序列之后。如果核心实行IRQ,则通过断言IRQACK来启动VIC端口握手;如果判断该中断请求为FIQ,则不断言IRQACK,并且不发起VIC端口握手。
3. Ignores the value of the nFIQ input until the IRQ interrupt entry sequence is completed if it has decided that the interrupt is an IRQ.如果判断该中断请求为IRQ, 则忽略nFIQ输入值直到完成IRQ中断入口序列。
4. Samples the IRQADDR input bus when both IRQACK and IRQADDRV are sampled asserted. The interrupt entry sequence proceeds with this value of IRQADDR.当IRQACK和IRQADDRV都被抽检为断言的,则对IRQADDR输入总线进行采样,中断入口序列随IRQADDR值进行。
5. Ignores the nIRQ signal while IRQADDRV is HIGH. This gives the VIC time to deassert the nIRQ signal if there is no higher priority interrupt pending.当IRQADDRV信号为高电平时,忽略nIRQ信号。当此间没有更好优先级的中断请求,这就给了VIC时间来解除nIRQ信号的认定。
6. Ignores the nFIQ signal while IRQADDRV is HIGH.当IRQADDRV为高电平时,忽略nFIQ信号。

【LZ,这么难得翻译,这么专业的翻译,如果你还有分,不再给50~100分都说不过去。】

【英语牛人团】奉献,脑力结晶,满意请记得及时采纳哦,谢谢^_^追问有的地方翻译的有点牵强吧?从哪翻译的????追答擦 我一字一字翻译的。我不是计算机专业的,为了你这翻译在google搜了一大片文章参考。。。追问你是什么专业的?追答外贸的,哥们这半天也只有我有这耐心为你细心琢磨翻译了`辛苦不说了 这翻译太专业,难度大追问外贸的怎么翻译英文来了?追答谁规定翻译只能翻译专业的来翻译了吗?许多英语专业的英语未必有我好!追问其实,我今天才把这个交上去,这只是我翻译其中的一部分,差不多十分之一。我们十三个人翻译,总共769页,给你的就是其中一页,嘿嘿
虽然我交了,但分还是给你吧,比我翻译的好些,呵呵
我们还有500多页没翻译呢,你还要不?追答你这个` 搞一篇还可以,太多了吃不消。
我刚刚搜过一些这方面的文章,到处都是计算机程序的缩写,估计你其他的文章都是陌生的计算机程序,我得一个个查,没时间 吃不消呀

并且这么多这么专业,你在这上面是找不着人翻译的,除了自己,你就只能花钱找这方面的专业翻译了。追问哈哈,好吧
