  • Publication number: 20020199083
    Abstract: A high code-density microcontroller architecture with changeable instruction formats has a memory for storing compressed instructions each including a group prefix and at least one index. An instruction decompressor is provided for decompressing the compressed instructions to be executed into original instructions. The instruction decompressor includes a plurality of instruction group decoding tables, each being stored with the original instructions of a predetermined type. One instruction group decoding table is selected based on the group prefix of the compressed instruction for searching the corresponding original instruction therein by the index of the compressed instruction.

  • Patent number: 6301651
    Abstract: The present invention provides a stack machine for executing a plurality of instructions one by one. The stack machine comprises an operation folder and an execution unit. The operation folder is used for checking if one or more instructions of a predetermined number of instructions following a specific instruction in a predetermined sequence can be folded with the specific instruction according to a POC folding rule. If they are foldable, these instructions will be combined to form a new instruction. The execution unit is used for executing instructions which cannot be folded by the operation folder or new instructions generated by the operation folder one by one. The instructions are folded to enhance operation efficiency of the stack machine.
