摘要
A Reduced Instruction Set Computing (RISC) processor is capable of emulating operation of a floating-point register stack. The RISC processor may include a floating-point register file containing a plurality of floating-point registers, a decoding section for decoding operation instructions, and a floating-point operation section. The RISC processor may also include a control register for controlling status of floating-point registers, and for controlling the decoding section and the floating-point operation section, to thereby emulate a floating-point register stack using the floating-point register file. The decoding section may include a pointer register for maintaining a stack operation pointer, and for storing a value of the stack operation pointer. The floating-point operation section may also include a pointer operation module for operating the pointer register, for emulating stack operation of the stack pointer of the pointer register, and for modifying and monitoring the stack pointer during emulation of floating-point register stack.
