- This paper describes on a design and implement tion of ASIC to integrate with high-quality voice over wireless LAN for the application of hand-held terminal, which is based on the wideband speech codec algorithm and IEEE 802.11e-based QoS mechanism. The target of this work mainly focused on the single chip integration for VoIP terminal providing the differentiated high-quality internet telephony service through wireless LAN. In the design of ASIC, ARM926EJ is adopted for a high-performance single RISC core to remove additional high-cost DSP device. Also wireless MAC and PHY layer based on IEEE802.11a, b, and g had designed and implemented on this device.
