The Lattice Semiconductor AHB-Lite Interconnect Module is a fully parameterized soft IP for high performance, low latency interconnect fabric for AHB-Lite system. It can be used to connect one or more AHB-Lite bus master to one or more AHB-Lite bus slaves.
It allows multiple bus masters to access different slaves in parallel without the need for arbitration. Slave-side arbitration is implemented for each slave port of the module to maximize parallelism.
The AHB-Lite Interconnect module supports round-robin based and fixed priority based arbitration when multiple bus masters access the same slave port. The arbitration completes in one clock cycle, which mean the transaction will be delayed by one clock cycle when arbitration occurs.
