1394 * AN OVERVIEW OF MXU EXTENSION INSTRUCTION SET
1395 * ============================================
1397 * MXU (full name: MIPS eXtension/enhanced Unit) is an SIMD extension of MIPS32
1398 * instructions set. It is designed to fit the needs of signal, graphical and
1399 * video processing applications. MXU instruction set is used in Xburst family
1400 * of microprocessors by Ingenic.
1402 * MXU unit contains 17 registers called X0-X16. X0 is always zero, and X16 is
1403 * the control register.
1405 * The notation used in MXU assembler mnemonics:
1407 * XRa, XRb, XRc, XRd - MXU registers
1408 * Rb, Rc, Rd, Rs, Rt - general purpose MIPS registers
1409 * s12 - a subfield of an instruction code
1410 * strd2 - a subfield of an instruction code
1411 * eptn2 - a subfield of an instruction code
1412 * eptn3 - a subfield of an instruction code
1413 * optn2 - a subfield of an instruction code
1414 * optn3 - a subfield of an instruction code
1415 * sft4 - a subfield of an instruction code
1417 * Load/Store instructions Multiplication instructions
