- W2349623021 abstract "In order to get a high quality and low cost speech coder for videophone system, an ASIC (Application Specific Integrated Circuit) was designed using DSP core. The speech coder complies with ITU T Recommendation G.723.1 (dual rate speech coder for multimedia communications transmitting at 5.3 6.3[KG5x]kbit/s) . According to the features of the G.723.1 algorthm and the architecture of the ASIC, some optimizations were used to reduce the computation complex and the memory size. The worst case which would cost maximum computation amount was simulated to ensure the coder can work properly in this case. The chart of the coder and its performance were presented. There is still enough resource left in this ASIC to implement the MODEM and the echo cancellator." @default.
