PCI-to-ISA Bridge
Block Diagram

Overview
The PCI-to-ISA bridge functions as a PCI target on the PCI bus. PCI transactions addressed to this target are forwarded to the ISA bus. If it is a read transfer, the core waits for all read data from the ISA slave and returns the data to the PCI bus. If it is a write transfer, the core posts the write data to its internal write buffer, terminates the PCI bus, and then writes the data to the ISA slave. With a typical PCI bus running at 33 MHz, this core operates the ISA bus at one-fourth the frequency of the PCI bus. The ISA bus operates at 8.33 MHz. The PCI-to-ISA bridge core supports 8-bit and 16-bit ISA bus devices, while the PCI bus is 32-bits wide. The core is capable of taking one PCI transfer and converting it into four or two transfers on the ISA bus. This megafunction sizes vary with features and customization. Eureka Technology can customize designs according to specific user requirements.
