摘要

先进电信应用的基带处理面临两个相互矛盾的问题。第一个是所需的灵活性,单个协议的模式数量呈爆炸式增长(例如3GPP-LTE的63种模式),单个芯片支持的协议数量(2010年为10种)以及需要在协议之间切换的新应用程序。第二个问题与性能和功耗有关:性能需求正在爆炸式增长(现在需要高达100GOPS),而功耗限制正在减少(大约500mW)。

A 477mW NoC-based digital baseband for MIMO 4G SDR
Baseband processing for advanced Telecom applications have to face two contradictory issues [1]. The first one is the flexibility required, with the exploding number of modes for a single protocol (e.g. 63 for 3GPP-LTE), the number of protocols to be supported by a single chip (≫10 in 2010) and new applications requiring a handover between protocols. The second concern is related to performance and power consumption: performance demands are exploding (up to 100GOPS are now required) with decreasing power consumption constraints (roughly 500mW).
