继在LTE手机基带市场上取得大成功后，Tensilica最近宣布，它最新开发出的针对基带SoC设计的Connx BBE32UE DSP IP正在推动向LTE-Advanced的升级，并已向一些领先供应商提供样品。
当ConnX BBE32UE DSP内核与Tensilica基带数据层处理器(DPU)一起配搭使用时，可以不到200mW的功耗实现一个完全可编程的、灵活的LTE-Advanced Modem。它也可用于支持2G、3G、LTE和HSPA+标准。
从LTE到LTE-Advanced的升级可能导致一个高达5倍的算法和数据率计算量增加，而且要求在一个很紧的功耗预算内实现。Tensilica已经与领先的手机制造商一起合作，针对用户端设备要求的算法优化ConnX BBE32UE的架构和指令集。
“Tensilica已经在LTE市场上取得了显著的成功，而且这一新产品看起来很适合LTE-Advanced用户端设备，”Forward Concepts总裁Will Strauss表示，“Tensilica理解LTE-Advanced的功率预算很紧，并已利用其定制处理器技术来满足这一挑战。”
Tensilica's flexible, processor-based solution is ideal for LTE-Advanced because the new algorithms may well need changing during field and interoperability testing. Previous design methods with hardwired implementations will not be able to provide the flexibility of algorithm updates, and most conventional wireless communications DSPs will fail to meet the power budget. With this new, very low-power DSP core and Baseband DPUs, Tensilica can offer system developers a path to implement flexible, ultra-low-power PHY systems.
Data bandwidth, an important criterion for LTE-Advanced User Equipment applications, is enhanced in the ConnX BBE32UE through the use of dual 256-bit load/store units. Additionally, designers can use Tensilica's proprietary Port (general-purpose I/O) and Queue interfaces to directly connect hardware blocks to the processing ALUs. This allows single cycle dedicated access without the need to go over a system bus, hence reducing the required clock frequency and power consumption.
"Our new ConnX BBE32UE IP core helps us reach new performance levels at the low power required for handset design," stated Eric Dewannain, Tensilica's vice president and general manager, baseband business unit. "We are excited about our design activity with major handset OEMs and IC manufacturers and appreciate their input as we worked to meet the challenging performance/power/area LTE-Advanced handset modem requirements."
Like other members of Tensilica's ConnX family of DSPs, the ConnX BBE32UE is fully programmable in C. It is software compatible with other ConnX DSPs and supported by an optimized DSP library.
While early access customers now have access to ConnX BBE32UE, general product release is planned for the third quarter of 2012.
