Command executing result storage structure for processor

Abstract

The invention provides a command executing result storage structure for a processor, which comprises the processor, a general purpose register file and a SPILL register file. The general purpose register file and the SPILL register pile are respectively connected with the processor; when the command executing result data volume of the processor is larger than the memory space of the general purpose register file, and a part of command executing results of the processor is saved in a general register file, and the other part of the command executing results of the processor are saved in the SPILL register file. By using the command executing result storage structure for the processor, when a register spills, the frequency of memory access can be effectively reduced, energy consumption can be reduced, spilled data can be quickly saved in the SPILL register file, and the executing efficiency of the processor can be improved.

Description

technical field [0001] The invention relates to a digital processing device, an electronic device and a processing system, in particular to a storage structure for a processor instruction execution result. Background technique [0002] A microprocessor is a semiconductor integrated circuit integrated on a chip, including the control and execution of a series of arithmetic and logic operations. In order to improve the processing capability of the processor, high-performance processors generally adopt a load-store structure. The load-store structure designs several register files in the processor core. The source and destination of all operations and calculations are registers. The data exchange inside and outside the processor core is completed by specific instructions such as load instructions and store instructions. The access speed of the main memory is very slow, and too many storage instructions will greatly affect the execution speed of the program. [0003] On the on...

Problems solved by technology

Therefore, the SPILL operation will greatly affect the execution speed of the program and increase power consumption.

[0004] However, some processors have multiple instruction execution units, such as the Magnolia processor, which is a Very Long Instruction Word (VLIW) processor, and these execution units need to share the register file, so the register overflow is more serious.
