第6章 DSP55xx芯片的指令系统及编程TMS320C55xx DSP指令集可分为六大类操作类型：装载和存储指令：交换、数据移动、堆栈操作及复制（DELAY）算术指令：加法、减法、加减、减加、乘法、乘累加、乘累减、移位、带条件加减、带条件移位，比较指令等程序控制指令：条件转移、无条件转移、重复、条件执行、CALL等bit控制指令：bit Test、Set、Clear、Complement扩展辅助寄存器指令：辅助寄存器数据移动、堆栈操作逻辑操作指令：与、或、非、异或、取反、逻辑移位其它操作指令：mmap、port6.1装载和存储指令 语法并行使能bit长度周期流水线执行单元Accumulator, Auxiliary, or Temporary Register Content SwapA unit ALUSWAP ARx, Tx
