摘要:
A data processing unit which can access a greater number of registers than registers addressable by an instruction to realize high-speed execution of a program. To this end, the data processing unit includes a greater number of floating point registers than the number of registers addressable by an ordinary instruction, a window start pointer register, a window start pointer valid register, a conversion circuit, when the window start pointer valid register has a value of 1, for converting a floating point register number in the instruction to a physical floating point register number and for changing a conversion pattern depending on the value of the window start pointer register, a window start pointer set instruction for setting a value at the window start pointer register, and floating point register pre-load and post-store instructions having a register field different in length from the ordinary instruction, and wherein the floating point register number specified by the register field is converted by the conversion circuit to the physical floating point register number on the basis of the value of the window start pointer register.

The data processing unit includes a greater number of physical floating point registers than the number of floating point registers accessible by an instruction, window start point register having a plurality of bits, 1-bit window start pointer valid register, conversion apparatus for converting a floating point register number in an instruction to a physical floating point register number when the value of the window start pointer valid register is 1, and changing the pattern of this conversion by a value obtained from the value of the window start pointer register or the value of a window stride designated in a specific instruction, and the value of the window start pointer register. Also provided is an instruction controller for detecting a window start pointer set instruction for setting a value to the window start pointer register, a floating point register pre-load instruction for converting the floating point register number in the instruction to a physical floating point register number by the conversion circuit from the value obtained from the value of the window start pointer register and the value of the window stride, and storing a main memory data in the physical floating point register indicated by the physical floating point register number.
摘要:
A data processor includes a register group having registers of the number larger than the number of registers which can be designated by a register specifier field of an instruction. The register group consists of a plurality of register queues with respect to logical register numbers designated in the instruction, each register queue including a plurality of physical registers. In the data processor, a physical register number forming section is provided for converting the logical register number to a physical register number in the register queue corresponding to the logical register number, by using queue control information designated in the register specifier field and read/write information decided by the kind of the instruction and the position of the register specifier field in the instruction.
摘要:
An arrangement having a register file having registers greater in number than those which are designated by an instruction, a pipeline ALU, a current window pointer and window number modifier operating in a register window mode, an element counter and address counter operating in a vector register mode, and register determining circuits for determining physical register numbers from the register numbers designated by an instruction in one of the two modes. Each register determining circuit has a first register determining circuit using an output of the window number modifier, for using the register file as a register window configuration, and a second register determining circuit using an output of the element counter, for using the register file as a vector register configuration. Physical registers of the register file are used as scalar registers in the register window mode, and used as vector registers in the vector register modes.
