pRU Registers and Bus System
The pRU bus system is connecting the various modules on the FPGA to a common master, the Microblaze Subsystem. Each of the modules is associated with a given BASE-ADDRESS specified in the pRU Control Interface Document. Note that several instances do exist for certain modules. E.g. there are one alpide_data instance for each ALPIDE chip connected to the pRU. To communicate with a specific instance one needs to add an offset of 0x1000 times the instance number to the module base address.
E.g. if you want to communicate with the
- 1st instance: <ALPIDE_DATA_BASEADDR>
- 2nd instance: <ALPIDE_DATA_BASEADDR> + (0x1000 * (2-1))
- 16th instance: <ALPIDE_DATA_BASEADDR> + (0x1000 * (16-1))

- Some of the aluminium traces on the flex cable broke by the tail of the cable (near the ZIF stiffener). Current design and possible modifications shows the current design and two possible modifications. It has been decided that new designs will use the design 1 modification and longer ZIF-stiffener (30 mm long).
