MmuPlugin

class MmuPlugin extends FiberPlugin with AddressTranslationService

Implement the RISC-V MMU using a N-way set associative TLB storage. This fit very well with FPGA which have distributed memories. For FPGA that do not have that, the MmuPortParameter can be configured to have a low number of sets or use 1 cycle delay to be inferable as block ram.

Plugins which uses the MmuPlugin can request TLB storage, then they can require the MmuPlugin to bind a new port on a existing pipeline using that TLB storage. A given TLB storage can be used by multiple MMU ports.

MMU miss will not by itself trigger a TLB refill. This is instead triggered by the TrapPlugin.
