摘要：
A method and apparatus for implementing a vocoder in a application specific integrated circuit (ASIC) is provided. The apparatus contains a DSP core that performs computations in accordance with a reduced instruction set (RISC) architecture. The circuit further includes a specifically designed slave processor to the DSP core referred to as the minimization processor. The apparatus further comprises a specifically designed block normalization circuitry.
