BIT RANGE ISOLATION INSTRUCTIONS, METHODS, AND APPARATUS

The application relates to bit range isolation instructions, methods, and apparatus, and discloses a processing element and a chip group system. A processing element receives an instruction indicatinga source operand and a destination operand and stores a result in the destination operand in response to the instruction. The result operand may have: (1) first range of bits having a first end explicitly specified by the instruction in which each bit is identical in value to a bit of the source operand in a corresponding position; and (2) second range of bits that all have a same value regardless of values of bits of the source operand in corresponding positions. Execution of instruction may complete without moving the first range of the result relative to the bits of identical value in thecorresponding positions of the source operand, regardless of the location of the first range of bits in the result. 本申请涉及位范围隔离指令、方法和装置，并揭示了种处理元件和芯片组系统。所述处理元件接收指示源操作数和目标操作数的指令。响应于该指令将结果储存在目标操作数中。该结果操作数可具有：(1)第位范围，具有由该指令显式指定的第端，
