Abstract
A stack processor comprises a data stack with a T register, an S register, and eight hardwired bottom registers which function in a circular repeating pattern. The stack processor also comprises a return stack containing an R register, and eight hardwired bottom registers which function in a circular repeating pattern. The circular register arrays described herein eliminate overflow and underflow stack conditions.
Claims37
A stack computer processor, comprising:
- a data stack, comprising at least one data register;
- and
- a return stack, comprising at least one return register;
- wherein:
- each of said data stack and said return stack can accommodate an 18 bit instruction word.
2 more elements
A method of manipulating a computer processor, comprising:
- inputting a plurality of instruction words into a corresponding plurality of instruction cells of said processor;
- and
- processing said plurality of instruction words, wherein:
- there is no overflow or underflow of instructions as a result of said inputting and said processing.
1 more element
A computer processor, comprising:
- an array of registers;
- and
- a shift register, wherein:
- said shift register comprises a plurality of one bit shift registers which are interconnected by electrical wires, and wherein said plurality of one bit shift registers is equal in number to a number of registers in said array of registers.
1 more element
A computer processor, comprising:
- an array of registers;
- and
- a bidirectional shift register hardwired to said array of registers, further comprising a plurality of one bit shift registers which are interconnected by electrical wires, and wherein said plurality of one bit shift registers is equal in number to a number of registers in said array of registers.
