In order to realize the signed addition operation with the spiking neural membrane system, it is necessary to solve the problem of complement representation of signed integers. In this paper, a spiking neural membrane system is designed for symbolic integer complement. Firstly, a spiking neural membrane system is designed to convert the negative integer code into complement code. Secondly, a spiking neural membrane system is designed to separate negative integers from non-negative integers. Finally, on the basis of the spiking neural membrane system with the separation of negative integer and non-negative integer, the spiking neural membrane system is designed for arbitrary integer complement. System simulation shows that the designed system can accurately calculate the complement of any signed integer. The solution of the current problem will be helpful to the design of the symbolic adder for the spiking neural membrane system.
