FUNCTIONAL DESCRIPTION

CORE: Core Module interconnects all the sub-modules in the SPI IP. Ports of core module are the top level ports for the SPI IP.

PRESCALER: Prescaler Module is used to divide the system clock based on the given prescaler value to drive the serial clock input for SPI.

FSM: FSM Module generates the SPI transcations on SPI Master based on commands from CSR block. This blocks implements all the features of SPI specifications.

ARB: ARB Module implements the arbiter to arbit between HCI and FSM access to CSR block.

HCI: HCI Module implements SPI Host controller FSM. The HCI FSM fetches the data from descriptor memory like SPI commands and transmit data bytes and it loads sampled read data bytes into descriptor memory.

XIP: XIP Module implements XIP/AIP mode operation with zero software overhead. XIP Module consists of functionality of both XIP and AIP mode. In XIP (Xecute In Place mode) executing the code directly from the serial flash memory .It will directly read from the Flash memory.In AIP (Access In Place) mode has both read and write operation will execute.It will write data into the flash device.XIP module is connected with soc Slave interface.

BOOT: Boot Module allows the host to read the data from the flash device after the power is on or after the hardware reset is done. It reads the data from the flash device without read command and address

CSR: CSR Module has all the registers. The contents of the registers are decoded and assigned to its respective output ports based on its functionality.
