The invention discloses a multi-floating point operand adding/subtracting operation controller which comprises a command word and operand writing timing sequence control module, an operand storage device, an operand reading timing sequence control module and an operation and output control module. The controller is in hard link with a control circuit by applying the FPGA design. The controller is selected by a system, the system sends out a writing timing sequence pulse under the action of a first WR, the system writes command words and operands of an order under the control of the timing sequence pulse, and the operands are stored into the operand storage device. After the first operand is written in, the controller sends out a reading timing sequence pulse, and under the control of the timing sequence pulse, the operation specified by the order is finished automatically. The process of computing the writing operands and the process of computing the reading operands are synchronously performed. After the fin
