Controller with bus

[codesavyani]

feat(Physical Design): Implementing a bus from the controller to solve utilization problem in the controller

Description

There is a utilization problem if we place controller on the left side of the resources because then the controller needs to be of height equal to all the resources.

These changes instead support controller to be below the resources in the physical design to decrease the overall area allotted to the controller.

To support this, a bus structure is implemented to pass instr, valid and activate signal to all the resources from the controller
