Therefore, on most architectures, a find-first-bit-set instruction is used to find the highest prioritybit set in one of five 32-bit words (for the 140 priorities).
因此，在大部分体系架构上，会使用一条find - first - bit - set指令在5个32位的字(140个优先级)中哪一位的优先级最高。

The array indices are stored in a 64-bit bitmap, and finding the highest priority task is very trivial.
数组的索引存储在一个64位的位图中，找到最高优先级的任务是很容易的。

It may be obvious that that's a top priority for you, but real world implementation may be a bit tricky.
