4G基带调制解调器等应用程序需要单芯片实施才能满足集成和功耗要求。这些应用程序需要具有实时限制，低功耗和低成本的高计算性能。随着电信标准的快速发展以及对多标准产品的需求不断增长，对柔性基带解决方案的需求正在增长。多芯片上系统系统（MPSOC）的概念非常适合在同一设备中的多个无线标准之间启用硬件重复使用。异质体系结构是众所周知的解决方案，但灵活性有限。根据两个异构软件定义的无线电（SDR）电信芯片组的经验，本文介绍了4G应用程序的均质处理器阵列（Genepy）平台。该平台是由智能调制解调器处理器（SMEP）构建的，该处理器（SMEP）与网络上的芯片互连。 SMEP以65nm的低功率CMOS实施，可以在400MHz时执行3.2 GMAC/s，内部带宽77 GBITS/s。将两种均质基因研究的实施与硅区域，性能和功耗方面进行了比较。结果表明，在4G移动终端的背景下，一种均质方法比异质方法更有效，更灵活。
Applications like 4G baseband modem require single-chip implementation to meet the integration and power consumption requirements. These applications demand a high computing performance with real-time constraints, low-power consumption and low cost. With the rapid evolution of telecom standards and the increasing demand for multi-standard products, the need for flexible baseband solutions is growing. The concept of Multi-Processor System-on-Chip (MPSoC) is well adapted to enable hardware reuse between products and between multiple wireless standards in the same device. Heterogeneous architectures are well known solutions but they have limited flexibility. Based on the experience of two heterogeneous Software Defined Radio (SDR) telecom chipsets, this paper presents the homoGENEous Processor arraY (GENEPY) platform for 4G applications. This platform is built with Smart ModEm Processors (SMEP) interconnected with a Network-on-Chip. The SMEP, implemented in 65nm low-power CMOS, can perform 3.2 GMAC/s with 77 GBits/s internal bandwidth at 400MHz. Two implementations of homogeneous GENEPY are compared to a heterogeneous platform in terms of silicon area, performance and power consumption. Results show that a homogeneous approach can be more efficient and flexible than a heterogeneous approach in the context of 4G Mobile Terminals.
