SPI to AXI4 Controller Bridge
The SPI to AXI4 Controller Bridge IP core enables easy inter-chip board-level interfacing between virtually any microcontroller (MCU) and Xilinx Zynq-7000 AP SoC and FPGAs through the Serial Peripheral Interface (SPI) bus. The SPI is a full-duplex synchronous four-wire serial interface between a single bus master, and one or more bus slave devices.
The SPI to AXI4 Controller Bridge IP core works as a SPI Slave controller and a 32-bit master controller on the ARM AMBA Advanced eXtensible Interface (AXI4) on-chip bus. It accepts and decodes a number of command SPI telegrams and allows the MCU to control peripherals implemented in the Zynq-7000 SoC or FPGA, or communicate with on-chip processors. Implemented bursting mechanism allows for large (2Kbytes) data transfers between on-chip and off-chip memories controlled by Xilinx programmable devices.
