基于ASIP的处理芯片和特定应用的ASIP指令集特点，选择了一种基于小区专用参考信号的TD-LTE下行信道估计算法的ASIP实现方案，并对这种方案完成了ASIP汇编实现。这种汇编实现具有较低的时间复杂度和定点运算误差，VCS仿真结果表明，该实现方案具有良好的实时处理能力。

A scheme for realizing Application Specific Instruction Set Processor (ASIP) is chosen, which is based on a channel estimation algorithm of cell-special reference signals in TD-LTE downlink. The ASIP chip contains a set of instructions for particular applications. Besides, the assembly language realization of the scheme is implemented, which exhibits lower time complexity and less fixed point operation error. Simulation results of Verilog Compiled Simulator (VCS) show that the scheme has a good real-time processing capability.
