Abstract

The invention discloses an implementation method of a non-flash memory interface circuit, a circuit, a storage medium and a terminal. The implementation method comprises the following steps: outputting logic data to the interface circuit in advance, and latching the logic data; and outputting corresponding logic data from latched logic data according to an enable signal received by the interface circuit. According to a technical scheme in the invention, the logic data is output to the interface circuit in advance, and a data latch of the interface circuit is used for latching the data, so thetime for waiting for a logic operation result when the data needs to be output is avoided; and the total delay of the technical scheme only comprises clock delay and data interface delay, so data output time delay is greatly reduced.

Description

technical field [0001] The invention relates to the field of data interface circuits, in particular to a method for realizing a non-type flash memory interface circuit, a circuit, a storage medium and a terminal. Background technique [0002] The interface circuit is widely used in integrated circuits and is responsible for communication with other external circuits. It usually includes clock and data buses, and uses the clock edge to determine the data bit. The SPI interface uses a clock edge to sample data in a single clock cycle. Each data line transmits one bit of data in one clock cycle. Usually the way to increase the transmission rate is to increase the clock frequency to transmit more data per unit time. However, a high clock frequency has higher requirements on the system, which will increase the cost and power consumption of the entire system. [0003] Generally, the DTR interface circuit can be used to solve the above problems. The DTR interface circuit uses the...
