900 Series processors include four different classes: N900 (32 bit), U900 (32 bit + MMU), NX900 (64 bit) and UX900 (64 bit + MMU). With MMU, UX900 supports heavyload operating systems such as Linux. 900 Series can be applied to edge computing, data center, networking, etc.
600-SMP(multi-core) is the configurable version of 600 Series support symmetric multi-processor (SMP) configuration.
