Abstract :
We present Lucent Technologies´ first dual-MAC DSP core. The 16-bit, fixed-point device features a datapath with two 16×16-bit multipliers and dual 40-bit adders that can all operate in one clock cycle to support compute-intensive DSP algorithms. In addition, the device includes special hardware to support all aspects of key communications applications such as wireless terminals, wireless infrastructure, and multichannel modems. The architecture offers a solution for these applications that balances performance, cost and power dissipation
