MXU instruction set is used in Xburst family + * of microprocessors by Ingenic. + * + * MXU unit contains 17 registers called X0-X16. X0 is always zero, and X16 is + * the control register. + * + * The notation used in MXU assembler mnemonics: + * + * XRa, XRb, XRc, XRd - MXU registers + * Rb, Rc, Rd, Rs, Rt - general purpose MIPS
