Abstract

In order to exploit the performance advantages of many core processors and solve more large-scale problems, this paper studied the parallelization of large integer multiplication on many core processors. Based on the parallel analysis of Written multiplication and Comba multiplication, this paper proposed a variety of solutions to solve the problem of load balancing when Comba multiplication is parallelized. Then according to the structural characteristics of SW26010, this paper selected the improved Comba multiplication based on Written multiplication. And the implementation process used some optimization me-thods such as vectorization, register communication and so on. The test results show that the improved Comba algorithm has better parallelism and can make good use of the performance advantages of the SW26010 many core processors.
