Arm声称，此次推出的Cortex-M55是其有史以来AI功能最强大的Cortex-M处理器，同时也是首款基于Armv8.1-M架构、内建Arm Helium向量处理技术的处理器。 与前几代Cortex-M系列处理器相比，Cortex-M55的机器学习性能最高可提升15倍，DSP性能可提升5倍，能耗比进一步提高。

The DCCS – “ARM D55” is a compact rectangular speaker that provides great sound when fitted inside our unique precision engineered enclosure which is designed to fit perfectly inside the rear of the Australian Railway Model's D55 locomotive body. This will produce the sound from the loco and not the tender.

Motor settings and sound volumes tuned to specifically suit the ARM D55 Class Model using the DCC Solutions speaker. Individual sounds slots and master sound volumes can be adjusted by the user to suit personal requirements. Full 28 function button remapping to suit your personal requirements. DCC Solutions High Performance Speaker delivering ...
