PCI Host Bridge

iW- PCI-Host Bridge provides an interface between the PCI bus and a generic local bus,which can be customizable to any bus architecture. It consists of two independent units, one handling transactions originating on the PCI bus, the other one handling transactions originating on the local bus.

PCI-PCI-Bridge

iW- PCI-PCI Bridge interfaces primary and secondary PCI buses. The primary interface should be connected to PCI bus nearer to the host processor. It functions as a slave on primary bus and as a master on secondary bus for transaction initiated on the primary side. At the same time it acts as a master on primary bus and as a slave on secondary bus for transaction initiated on the secondary side.

SDRAM Controller

iW-SDRAM Controller provides a simplified interface to the industry standard SDR SDRAM memory. It can be configured to support different standard SDR SDRAM chips.

DDR SDRAM Controller

iW-DDR SDRAM Controller provides the user with a simplified interface toindustry standard DDR SDRAM memory devices.

DDR2 Controller

iW-DDR2 Controller core performs initialization of the DDR2 memory and provides necessary commands for a memory read or memory write access. It acts as an interface between the memory device and DMA Interface.
