Abstract
A processor that reduces pipeline stall including a front end, a load queue, a scheduler, and a load buffer. The front end issues instructions while a first full indication is not provided, but otherwise stalls issuing instructions. The load queue stores issued load instruction entries including information needed to execute the issued load instruction. The load queue provides a second full indication when full. The scheduler dispatches issued instructions for execution except for stalled load instructions, such as when not yet been stored in the load queue. The load buffer transfers issued load instructions to the load queue when the load queue is not full. When the load queue is full, the load buffer temporarily buffers issued load instructions until the load queue is no longer full. The load buffer allows more accurate load queue full determination, and allows processing to continue even when the load queue is full.
