Dolphin Quad SPI Controller
Dolphin Technology provides Quad SPI Controller IP which enables access to a QSPI flash device through read, write and erase operations. The Quad SPI IP either controls a serial data link as a master, or reacts to a serial data link as a slave. The core operates in various data modes from 4 bits to 32 bits. The data is then serialized and then transmitted, either LSB or MSB first, using the standard 4-wire SPI bus interface or the extended Quad mode bus.
