Abstract [en]

Programmability will be increasingly important in future multi-standard radio systems. We are proposing an architecture for fully programmable baseband processing, based on a programmable DSP processor and a number of configurable accelerators which communicate via a configurable network. Acceleration of common cycleconsuming DSP jobs is necessary in order to manage wide-band modulation schemes. In this paper we investigate which jobs are suitable for acceleration in a programmable baseband processor supporting a number of common Wireless LAN and 3G standards. Benchmarking show that with the proposed set of accelerators, our architecture can support the discussed standards, including IEEE 802.11a 54 Mbit/s wireless LAN reception, at a clock frequency not exceeding 120 MHz.
