Description

The Roa Logic AHB-Lite APB4 Bridge is a fully parameterized soft IP interconnect bridge between the AMBA 3 AHB-Lite v1.0 and AMBA APB v2.0 bus protocols.

The AHB-Lite APB4 Bridge natively supports a single peripheral, however multiple APB4 peripherals may be connected to a single bridge by including supporting multiplexer logic – See the AMBA APB v2.0 Protocol specification. An APB4 Multiplexer IP implementing this capability is available from Roa Logic
