The VMESCmodule2 is a VME System Controller core designed for FPGA and ASIC integrations. The core contains VME Slave and Master functions as well as System Controller features such as bus timer, arbiter, IACK daisy-chain driver, system clock driver and provisioning for CSR. The VMESCmodule2 can be used either as a System Controller residing in slot 1 of a VME chassis or as a regular VME Slave or Master.
The AXI4 compliant user-side interface simplifies system integration. The core contains internal FIFOs and address mapping logic to bridge the VME to the AXI bus and vice versa. A dedicated AXI4-lite port is provided for independent CSR access.
