摘要： In some embodiments, a data structure may be received in a first processing system. The data structure may represent a plurality of instructions for a second processing system. For at least one instruction of the plurality of instructions, a determination may be made as to whether the instruction can be replaced by a compact instruction for the second processing system. A compact instruction may be generated if the instruction can be replaced by a compact instruction. In some embodiments, an instruction may be received in a processing system. A determination may be made as to whether the instruction is a compact instruction. A decompacted instruction may be generated if the instruction is a compact instruction.

摘要： A method of compressing instructions in a program may include extracting unique bit patterns from the instructions in the program and constructing a linear programming formulation or an integer programming formulation from the unique bit patterns, the instructions, and/or the size of a memory storage. The linear programming formulation or the integer programming formulation may be solved to produce a solution. The method may include compressing at least some of the instructions based on the solution by storing at least some of the unique bit patterns in a memory and placing corresponding indices to the memory in new compressed instructions.
