VME Slave Controller Core

The VMESmodule is a complete VME Slave Controller core bridging the VME bus and the local bus. The core contains a VME Slave, a VME interrupter, mailbox and semaphore registers, a local interrupt controller, provisioning for CR/CSR, and a generic local bus interface.

The VMESmodule is a building block for your custom VME slave design. The synchronous local bus interface eases system integration while the VME slave bridge already contains all necessary functions and features of a VME slave controller.

With this reach feature set, the VMESmodule is an excellent platform to base all your future Slave VME designs on.
