Fixed-point accumulation operation processing method and device and electronic equipment

The embodiment of the invention discloses a fixed-point accumulation operation processing method and device and electronic equipment, and the method comprises the steps: resetting an appointed flag bit of a state register,wherein the value of the reset specified flag bit is used for representing that data in a first data register does not generate saturated overflow; executing a fixed-point accumulation operation based on the first bit number, storing a fixed-point accumulation result in a first data register corresponding to the first bit number, wherein a speicified flag bit of the state register is set as a preset value when the fixed-point accumulation result in the first data register generates saturated overflow; reading the specified flag bit; if the specified flag bit is the presetvalue, executing the fixed-point accumulation operation again based on the second bit number, and storing the fixed-point accumulation result in a second data register corresponding to the second bitnumber, wherein the first
