Cadence Tensilica Fusion F1 DSP Stars in NB IoT ApplicationsCadence IP Blog - Paula Jones, CadenceJul. 03, 2018 |
Did you make it to MWC Shanghai? I didn’t, but I read about what was hot – narrowband (NB) IoT. Three of Cadence’s customers had Tensilica Fusion F1 DSP demos on the show floor.
Xinyi Information Technology, a China-based company, showed off the first single-core modem that integrates a CMOS power amplifier with the modem. Their Marconi X1 modem features an NB-IoT protocol stack from Huachang Technology, who was able to optimize the stack on the Fusion F1 DSP and reduce code size by 20 percent compared to other processor architectures.
Raphael Micro, from Taiwan, showcased the Fusion F1 DSP in its NB-IoT modem IC, which integrates RF radio and includes necessary firmware support. The Fusion F1 DSP allowed Rafael Micro to implement its modem with 36 percent lower power and 45 percent smaller code size compared to a competitive processor they also evaluated.
