KaiXian KX-5000 series 4-core processor

Zhaoxin KaiXian KX-5000 series 4-core processor is the latest generation of general SOC processor which is the first domestic CPU that supports DDR4 memory developed by Zhaoxin. It’s based on advanced 28nm CMOS process and the package size is 37.5mm x 37.5mm HFCBGA, with 4 CPU cores in KX-5000, dual-channel DDR4 high speed memory controller, 3D image accelerator, HD media decoder, display port and PCle3.0 lane, KX-5000 is compatible with main stream hardware. The CPU core adopts superscalar, multi-issue and out-of-order execution optimization, the architecture is compatible with x86 instruction sets, capable of supporting native 64-bit operating system as well as CPU virtualization technology (VT). By adding SM3, SMS4 cryptographic algorithm support in it, KX-5000 series 4-core processor is compatible with desktop, portable terminal and embedded solutions.
