    • A system for an orthogonal frequency division multiplexed (OFDM) equalizer, said system comprising a program memory, a program sequencer and a processing unit connected to each other, wherein the processing unit comprises an input selection unit, an arithmetic logic unit (ALU) and an output selection unit; further wherein the program sequencer schedules the processing of one or more symbol-carrier pairs input to said OFDM equalizer using multiple threads; retrieves, for each of the one or more symbol-carrier pairs, multiple program instructions from said program memory; generates multiple expanded instructions corresponding to said retrieved multiple program instructions; and further wherein said ALU performs said processing of the one or more symbol-carrier pairs using the multiple threads across multiple pipeline stages, wherein said processing comprises said ALU executing one or more arithmetic operations to process said expanded instructions using said multiple threads across the multiple pipeline stages.
    • 一种用于正交频分复用(OFDM)均衡器的系统,所述系统包括程序存储器,程序定序器和彼此连接的处理单元,其中处理单元包括输入选择单元,算术逻辑单元(ALU)和 输出选择单元; 其中所述程序定序器使用多个线程调度输入到所述OFDM均衡器的一个或多个符号 - 载波对的处理; 对于所述一个或多个符号 - 载体对中的每一个检索来自所述程序存储器的多个程序指令; 产生对应于所述检索的多个程序指令的多个扩展指令; 并且其中所述ALU使用跨多个流水线级的多个线程执行所述一个或多个符号 - 载体对的所述处理,其中所述处理包括所述ALU执行一个或多个算术运算以使用所述多个线程上的所述多个线程来处理所述扩展指令 流水线阶段
