Unicore

Unicore is a computer instruction set architecture designed by the Microprocessor Research and Development Center (MPRC) of Peking University in the PRC.

[1] The CPU is integrated into a fully functional SoC to make a PC-like system.

[2] The processor is very similar to the ARM architecture, but uses a different instruction set.

[3][better source needed] It is supported by the Linux kernel as of version 2.6.39.

The load/store multiple instruction can only access half of the register set, depending on the H bit.
