The 386 microcode sequencer has a one-cycle pipeline delay: when a jump or RNI (run next instruction) is decoded, the micro-instruction immediately after it has already been fetched and will execute before the jump takes effect. This "delay slot" is a basic property of the sequencer, and the microcode is written to fill it with useful work rather than waste a cycle on a bubble. The examples in the PTSAV section above show this: at 582/5AE, the micro-instruction after LCALL executes before the subroutine begins.
但效果也很快显现:通胀从1990年的7650%降至1992年的约50%,到1990年代末已回落至个位数;经济重新恢复增长,秘鲁重返国际金融体系,外资开始进入;同时制度改革启动,贫民区土地登记、企业注册简化、经济逐步正规化。
