如果您已经阅读了我的其他question，那么您将知道我本周末花了6502 CPU模拟器作为编程练习。
CPU模拟器大部分都是完整的，并且在我的有限测试中似乎相当准确，但运行速度非常快，我想将其降低到机器的实际时钟速度。
我目前的测试循环是：
// Just loop infinitely.
while (1 == 1)
{
CPU.ClockCyclesBeforeNext--;
if (CPU.ClockCyclesBeforeNext <= 0)
{
// Find out how many clock cycles this instruction will take
CPU.ClockCyclesBeforeNext = CPU.OpcodeMapper.Map[CPU.Memory[CPU.PC]].CpuCycles;
// Run the instruction
CPU.ExecuteInstruction(CPU.Memory[CPU.PC]);
// Debugging Info
CPU.DumpDebug();
Console.WriteLine(CPU.OpcodeMapper.Map[CPU.Memory[CPU.PC]].ArgumentLength);
// Move to next instruction
CPU.PC += 1 + CPU.OpcodeMapper.Map[CPU.Memory[CPU.PC]].ArgumentLength;
}
}
正如您所知，每个操作码都需要一段特定的时间才能完成，因此在计算CPU周期时钟之前，我不会运行下一条指令。这提供了操作码之间的适当时序，只是整个事情都在快速运行。
目标CPU速度是1.79mhz，但是我想要时钟问题的任何解决方案来保持速度为1.79mhz，即使我增加了复杂性，所以我不需要调整它。
有什么想法吗？
答案 0 :(得分：13)
我多年前写了一个Z80仿真器，并且为了循环精确执行，我将时钟速率分成许多小块，并且核心执行了很多时钟周期。在我的情况下，我把它绑定到我正在模拟的游戏系统的帧速率。每个操作码都知道执行了多少个周期，并且核心将继续运行操作码，直到执行了指定的周期数。我有一个外部运行循环，它将运行cpu核心，并运行模拟系统的其他部分，然后休眠直到下一次迭代的开始时间。
编辑：添加运行循环的示例。
int execute_run_loop( int cycles )
{
int n = 0;
while( n < cycles )
{
/* Returns number of cycles executed */
n += execute_next_opcode();
}
return n;
}
希望这有帮助。
答案 1 :(得分：8)
查看原始的quicktime文档以获取灵感。
这是很久以前写的，当时显示的视频只是以足够高的速度交换静止帧，但苹果公司认为他们需要一个完整的时间管理框架。设计起初看起来过度设计，但它让它们处理不同的速度要求并使它们保持紧密同步。
幸运的是，6502具有确定性的时间行为，每个指令所用的确切时间都有详细记录;但它并不是一成不变的。一些指令需要2个周期，其他3.就像QuickTime中的帧一样，视频没有“每秒帧数”参数，每帧都表示它想要在屏幕上显示多长时间。
由于现代CPU是如此不确定，并且多任务操作系统甚至可以冻结几毫秒（虚拟内存！），如果您落后于计划，或者如果您可以休息几毫秒，则应该保留一个选项卡。
答案 2 :(得分：4)
正如jfk所说，最常见的方法是将cpu速度与（模拟）视频输出的垂直刷新联系起来。
选择每个视频帧运行一些周期。这通常是特定于机器的，但您可以通过以下方式计算它：
cycles = clock speed in Hz / required frames-per-second
然后你也可以进行睡眠，直到视频更新被点击，此时你开始接下来的n个CPU仿真周期。
如果您特别模仿某些内容，那么您只需要查看fps速率和处理器速度即可实现这一点。
编辑：如果您没有任何外部时序要求，那么仿真器尽可能快地运行是正常的。有时这是一种理想的效果，有时不会：）
答案 3 :(得分：3)
我会使用时钟周期来计算时间，然后让他们在时间上睡觉。当然，要做到这一点，你需要一个高分辨率的时钟。他们这样做的方式是在旋转循环中将CPU加速。
答案 4 :(得分：2)
是的，正如大多数时候所说的那样，你不需要CPU模拟器以与真实物体相同的速度模拟指令。用户感知的是计算的输出（即音频和视频输出），因此您只需要与这些输出同步，这并不意味着您必须具有精确的CPU仿真速度。 / p>
换句话说，如果视频输入的帧速率是50Hz，那么让CPU模拟器以尽可能快的速度运行以绘制屏幕，但一定要以正确的速率输出屏幕帧（ 50赫兹）。从外部角度来看，您的模拟器正在以正确的速度进行模拟。
在Windows或Linux等多任务操作系统上尝试即使在执行时也能完全循环是没有意义的，因为仿真器指令时间（老式80s CPU的简单1uS）和现代操作系统的调度时隙是可比较的。
尝试以50Hz的速率输出内容是一项更简单的任务，你可以在任何现代机器上做得很好
答案 5 :(得分：0)
如果实现音频仿真，并且音频输出与系统/ CPU时钟相关联，则可以使用另一个选项。特别是我知道这就是8位Apple的情况[计算机。
通常声音是在固定大小的缓冲区（固定时间）中生成的，因此这些缓冲区的操作（生成数据等）可以通过同步原语与CPU吞吐量相关联。
答案 6 :(得分：0)
我正在制作一些更通用的用例，例如将时间转换为估计数量的指令的能力，反之亦然。
