虽然指令集主要是将它们拆解成4个32位的字，不过对于这种情况的处理已经有足够的支持了。
The instruction set is primarily geared around dividing it into four 32-bit words, but there is enough support to handle any of these situations.
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。
Therefore, on most architectures, a find-first-bit-set instruction is used to find the highest priority bit set in one of five 32-bit words (for the 140 priorities).
