SPI, known also as a "spy" bus, is a synchronous serial data link standard developed by Motorola company. As the SPI operates in full duplex mode, it's been also called a "four-wire" serial bus, contrasting with three-, two-, and one-wire serial buses.
As far as Serial Peripheral Interface gives wide developing possibilities, Digital Core Design masterminded 3 controllers, which differs in features and destination. The most powerful IP Core - DSPI is SPI Master/Slave controller supporting all 4 SPI Transmission Modes, errors detection, interrupt generation and flexible transmission speed selection. And if it's not enough, there's also The DSPI_FIFO, which supports all the features of DSPI and transmission/reception FIFOs, to significantly reduce the CPU time
