Abstract:
An SPI access control method and system, and a computing device and a storage medium. The SPI access control method comprises: when an SPI master device requests access to an SPI slave device, intercepting an access signal, which is sent by the SPI master device to the SPI slave device, wherein the access signal comprises a logical address and a signal source flag; modifying the logical address according to the signal source flag, and mapping, to a storage extent corresponding to the modified logical address, a request for access to the SPI slave device by the SPI master device; and by taking, as an access extent, the storage extent corresponding to the modified logical address, establishing a communication connection between the SPI master device and the access extent. By means of the present invention, an access request of an SPI master device can be mapped to one of storage extents in an SPI slave device, such that the effect of a plurality of SPI slave devices is achieved by using a single SPI slave device, thereby reducing costs, and also overcoming the problem of installation limitations.
