1.6.1.9.1. Memory Block (ROM)

The control unit is a finite state machine (FSM) that works with multiple memory blocks (ROMs).

Each ROM holds the configuration data required to configure the external converter or clock devices for each SPI slave. A memory initialization file (MIF) contains the initial values for each address in the memory. Each memory block requires a separate file. You can create the MIF using the text editor tool in the Quartus® Prime software.

Figure 19.  Example of MIF Format and Content


The initial values for each address and sequence is defined based on the requirement of the external converter and clock devices. The example above is based on 24-bit SPI write-only programming.

The last word must not be a valid data and must be set to all 1's to indicate the end of the MIF or programming sequence. This is because each converter device may have a different number of programmable registers and hence involves a different number of MIF words. In this design example, three ROMs are used by default for each external ADC, DAC, and clock devices. If either one of the device is not used, a single word MIF with all 1's can be created.
Note: The MIFs in this design example is an example for a particular converter device. You must define the MIF content based on the requirement of the external converter devices.
