摘　　要：可重构计算中硬件任务布局产生的碎片是影响任务成功布局和系统资源利用率的关键因素之一.本文提出一种针对布局碎片的量化方法QFTD,核心是先将碎片进行三维抽象,再对其三维量化得到待布局任务的碎片量化值.仿真结果表明,将该方法运用于布局器可明显降低任务拒绝率和提高硬件资源利用率.The fragments of placement for reconfigurable hardware task in reconfigurable computing are one of critical factors to affect task to be placed successfully and system resource utilization.An approach named of QFTD that aims at quantifying the fragments of task placement was proposed in this paper,and its kernel is to abstract the fragments in a 3D angle,then to quantify the fragments′ value of task waiting to be placed.Emulation results showed that when applied to placer it can markedly reduce task rejection ratio and increase the chip resource utilization.
