Title:
COMPILATION PROGRAM AND INFORMATION PROCESSING DEVICE
Document Type and Number:
Japanese Patent JP2021093012
Kind Code:
A
Abstract:
To optimize loop processing in an appropriate way.SOLUTION: Based on a loop instruction string 1, an information processing device 10 generates a first SIMD instruction string 2 that describes loop processing that repeats processing for executing operations in parallel according to an SIMD instruction for one or more elements enabled by a mask. Next, the information processing device 10 stores a plurality of discontinuous elements in the alignment in continuous areas in an SIMD register, and generates a second SIMD instruction string 3 that describes loop processing that repeats processing for executing operations in parallel according to the SIMD instruction for a plurality of elements in the SIMD register. Then, the information processing device 10 selects an instruction string to be included in a compiled program based on the first SIMD instruction string 2, the second SIMD instruction string 3, and processing time.SELECTED DRAWING: Figure 1
