SIMD TYPE PARALLEL DATA PROCESSOR, DATA SORT METHOD AND PROCESSING ELEMENT

摘要

Sorting efficiency is improved. When an exchange determination signal generated by executing a first subtraction exchange command is a predetermined value, numerical data of a register (12i) of a self PE (11i) is exchanged with a numerical data of a register (12i+1) of a PE (11i+1) located on the right. When an exchange determination signal generated by executing a second subtraction exchange command is a predetermined value, numerical data of a register (12i) of a self PE (11i) is exchanged with a numerical data of a register (12i-1) of a PE (11i-1) located on the left.
