+ *       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.
+ *
+ *
+ *     The notation used in MXU assembler mnemonics
+ *     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ *  Register operands:
+ *
+ *   XRa, XRb, XRc, XRd - MXU registers
+ *   Rb, Rc, Rd, Rs, Rt - general purpose MIPS registers
+ *
+ *  Non-register operands:
+ *
+ *   aptn1 - 1-bit accumulate add/subtract pattern
+ *   aptn2 - 2-bit accumulate add/subtract pattern
+ *   eptn2 - 2-bit execute add/subtract pattern

- *       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.
- *
- *
- *     The notation used in MXU assembler mnemonics
- *     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- *
- *  Register operands:
- *
- *   XRa, XRb, XRc, XRd - MXU registers
- *   Rb, Rc, Rd, Rs, Rt - general purpose MIPS registers
- *
- *  Non-register operands:
- *
- *   aptn1 - 1-bit accumulate add/subtract pattern
- *   aptn2 - 2-bit accumulate add/subtract pattern
- *   eptn2 - 2-bit execute add/subtract pattern
- *   optn2 - 2-bit operand pattern
- *   optn3 - 3-bit operand pattern
- *   sft4  - 4-bit shift amount
- *   strd2 - 2-bit stride amount
- *
- *  Prefixes:
- *
- *   Level of parallelism:                Operand size:
- *    S - single operation at a time       32 - word
- *    D - two operations in parallel       16 - half word
- *    Q - four operations in parallel       8 - byte
- *
- *  Operations:
- *
- *   ADD   - Add or subtract
- *   ADDC  - Add with carry-in
- *   ACC   - Accumulate
- *   ASUM  - Sum together then accumulate (add or subtract)
- *   ASUMC - Sum together then accumulate (add or subtract) with carry-in
- *   AVG   - Average between 2 operands
- *   ABD   - Absolute difference
- *   ALN   - Align data
- *   AND   - Logical bitwise 'and' operation
- *   CPS   - Copy sign
- *   EXTR  - Extract bits
- *   I2M   - Move from GPR register to MXU register
- *   LDD   - Load data from memory to XRF
- *   LDI   - Load data from memory to XRF (and increase the address base)
- *   LUI   - Load unsigned immediate
- *   MUL   - Multiply
- *   MULU  - Unsigned multiply
- *   MADD  - 64-bit operand add 32x32 product
- *   MSUB  - 64-bit operand subtract 32x32 product
- *   MAC   - Multiply and accumulate (add or subtract)
- *   MAD   - Multiply and add or subtract
- *   MAX   - Maximum between 2 operands
- *   MIN   - Minimum between 2 operands
- *   M2I   - Move from MXU register to GPR register
- *   MOVZ  - Move if zero
- *   MOVN  - Move if non-zero
- *   NOR   - Logical bitwise 'nor' operation
- *   OR    - Logical bitwise 'or' operation
- *   STD   - Store data from XRF to memory
- *   SDI   - Store data from XRF to memory (and increase the address base)
- *   SLT   - Set of less than comparison
- *   SAD   - Sum of absolute differences
- *   SLL   - Logical shift left
- *   SLR   - Logical shift right
- *   SAR   - Arithmetic shift right
- *   SAT   - Saturation
- *   SFL   - Shuffle
- *   SCOP  - Calculate x’s scope (-1, means x<0; 0, means x==0; 1, means x>0)
- *   XOR   - Logical bitwise 'exclusive or' operation
- *
- *  Suffixes:
- *
- *   E - Expand results
- *   F - Fixed point multiplication
- *   L - Low part result
- *   R - Doing rounding
- *   V - Variable instead of immediate
- *   W - Combine above L and V

- *     The opcode organization of MXU instructions

- *
- * The bits 31..26 of all MXU instructions are equal to 0x1C (also referred

- * other bits up to the instruction level is as follows:
