Therefore, on most architectures, a find-first-bit-setinstruction is used to find the highest priority bit 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。

It only CARES that the ones and zeros are consistent with its instructionset and address space.
它只关心这些零一指令是否与其指令集和地址空间一致。

Its successor was the 4040 processor (released in 1974), which had an expanded instructionset, program memory, register set, and stack.
