We present extensions to the programmable DSP architectures for reduced power dissipations. These extensions address power reduction in both external and internal buses, which form a major component of power dissipation in pipelined programmable processors such as DSPs. We present two techniques to reduce power dissipation in the program and data memory address buses, a technique to reduce cross-coupling related power dissipation in the program memory data bus and a technique for reducing power dissipation in the input buses of the ALU. We present results in terms of power savings using these techniques
