These instructions were introduced in the Cyrix 6x86MX and MII processors, and were also present in the MediaGXm and Geode GX1 [53] processors. (In later non-Cyrix processors, all of their opcodes have been used for SSE or SSE2 instructions.) These instructions are integer SIMD instructions acting on 64-bit vectors in MMX registers or memory.
This is a list of the instructions in the instruction set of the Common Intermediate Language bytecode. Opcode abbreviated from operation code is the portion of a machine language instruction that specifies the operation to be performed. Base instructions form a Turing-complete instruction set.
The only register on an 8051 that is not memory-mapped is the 16-bit program counter (PC). This specifies the address of the next instruction to execute. Relative branch instructions supply an 8-bit signed offset which is added to the PC. Eight general-purpose registers R0–R7 may be accessed with instructions one byte shorter than others.
An illegal opcode, also called an unimplemented operation, [1] unintended opcode [2] or undocumented instruction, is an instruction to a CPU that is not mentioned in any official documentation released by the CPU's designer or manufacturer, which nevertheless has an effect.
The "Classic" core has only the zero-operand form of the LPM instruction, which is equivalent to LPM r0,Z. "Classic plus" adds the MOVW instruction for moving register pairs, and the more general form of the LPM instruction (LPM Rd,Z and LPM Rd,Z+) which permit an arbitrary destination register and auto-increment of the Z pointer.
