The invention discloses a power consumption prediction system and method for a high-density computing system, and the method comprises the steps: monitoring the power consumption of a direct memory access module and an arithmetic unit in real time through power consumption state collectors disposed in the direct memory access module and the arithmetic unit; a power consumption predictor arranged in an instruction queue module and/or a direct memory access module predicts a power consumption increment caused by a scheduling instruction, so that power consumption transient is avoided. The system and the method can be suitable for different operation system architectures, support complex operation types and have universality. 本发明公开一种用于高密计算系统的功耗预测系统及方法，其通过设置于直接内存访问模块以及运算单元中的功耗状态收集器实时监测所述直接内存访问模块以及运算单元的功耗，然后基于监测得到的功耗值，通过设置于指令队列模块和/或直接内存访问模块中的功耗预测器预测调度指令引起的功耗增量，进而避免功耗瞬变。该系统及方法能够适用于不同的运算系统架构，支持复杂的运算类型，具有普适性。
