A.8 Active List
The R10000 processor's active list is a program-order list of decoded instructions. For each instruction, the active list indicates the physical register which contained the previous value of the destination register (if any). If this instruction graduates, that previous value is discarded and the physical register is returned to the free list. The active list records status, such as those instructions that have completed, or those instructions that have detected exceptions. Instructions are appended to the bottom of the list as they are decoded and instructions are removed from the top as they graduate.
