STACK COMPUTERS WITH PREFIX COMMANDS Russian patent published in 2016 - IPC G06F15/76 

FIELD: information technology.

SUBSTANCE: invention relates to digital data processing and intended for use in computers, which include computers stack. Technical result is achieved by the stack computer, which comprises an ALU, RAM, instruction decoder, register file to the data stack and direct access to the elements of the stack, the top element of the stack register, the register operand multiplexers at the inputs and output of the ALU. Instruction decoder decodes and executes commands the computer, as well as byte prefix command operands and constants. Team prefix operand specifies the stack or memory location that instruction decoder uses both the source and the receiver processing the next command. Command prefix constant instruction decoder uses as a constant following command data or to expand the ranks of its information field.

EFFECT: technical result is to reduce the number of commands and the time data in the memory.
