Abstract

The invention discloses an enhanced SPI device and a method for data transmission by using the device. The device comprises a peripheral bus interface module, a register configuration module, a data access module, a reset module, a frequency-division module and a data receiving and transmitting module. The peripheral bus interface module is separately connected with the register configuration module and the reset module, and the register configuration module is connected with the data receiving and transmitting module through the data access module and the frequency-division module respectively. The method comprises the steps that the state of an Espi register is read; according to the read state, the register is configured, and data is written into the Espi; the written data is verified; the Espi data which is successfully verified is read. by means of the device and the method, the data transmission speed can be obviously increased.

Description

technical field [0001] The invention relates to the technical field of chip design, in particular to an enhanced SPI device and a data transmission method using the device. Background technique [0002] There are many standards in the interface of modern EDA (Electronics Design Automation, electronic design automation) peripheral electronic devices, such as SPI (serial peripheral interface, serial peripheral interface), I2C (Inter-Integrated Circuit, integrated circuit bus), UART (Universal Asynchronous Receiver / Transmitter, Universal Asynchronous Receiver) and so on. [0003] Such as figure 1 As shown, taking the SPI interface as an example, the master (master) sends control signals to the SPI core, and the data is processed by the shift register (shift register) and sent to the SPI core. The entire SPI passes MOSI / MISO (MISO, master input slave output, master Item slave spi data line; MOSI, master output slave input, slave to master spi data line) serial data line is con...
