| 中文摘要: |
| 人工耳蜗是目前治疗深度或重度耳蜗性聋的唯一有效的办法,由体外语音处理器和植入体组成。介绍了一种基于商用现货原则(COTS,Commercial-Off-The-Shelf)的低功耗人工耳蜗体外语音处理器的设计与实现:系统选用低功耗立体声A/D芯片CS53L21实现前端处理和采集语音信号;利用通用16位定点DSP芯片TMS320VC5502实现语音处理CIS算法;借用RFID射频芯片MLX90121向植入体传输能量并与其进行双向数据通信。 |
| 英文摘要: |
| Cochlea implant which is composed of external body speech processor and internal receiver-stimulator can provide a sense of sound to people who are deaf or deeply hearing-impaired.Development of low power speech processor for cochlear implant based on Commercial-Off-The-Shelf(COTS) is described.The low power stereo A/D CS53L21 is used to collect the speech signal,the speech signal is processed by the TMS320VC5502 with CIS algorithm,and the RFID chip MLX90121 is used to communicate with the internal receiver-stimulator via RF link. |
