+ * AN OVERVIEW OF MXU EXTENSION INSTRUCTION SET
+ * ============================================
+ *
+ *
+ * MXU (full name: MIPS eXtension/enhanced Unit) is a SIMD extension of MIPS32
* instructions set. It is designed to fit the needs of signal, graphical and
* video processing applications. 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.
