Design and implementation of a DSP with multi-level low power strategies for cochlear implants

This paper presents the design and implementation of a low power digital signal processor(THUCID-SP-1)targeting at application for cochlear implants.Multi-level low power strategies including algorithmoptimization,operand isolation,clock gating and memory partitioning are adopted in the processor designto reduce the power consumption.Experimental results show that the complexity of the Continuous Inter-leaved Sampling(CIS)algorithm is reduced by more than 80% and the power dissipation of the hardwarealo...
