Abstract:Due to the lack of control instruction setting steps in traditional technology, the control accuracy is relatively low. In order to solve this problem, a double rate rate accurate control technology based on fitting is proposed. According to the rate formula, parallel bus is used to get double storage rate. Time sharing loading method is used to fit double storage rate data to facilitate the setting of control instructions. The control performance of MCU memory is analyzed, and the instruction set of double storage rate control is set. According to the control instruction, the time division storage and empty storage operation are corrected accurately, and the MCU memory's double rate is effectively controlled. The experimental results show that the precision of the technology can reach up to 98%, and the precision control standard for double rate can be achieved in the actual storage process.
