The PI7C9X794FCE is a high-speed dual-bus bridge interconnect that connects a peripheral bus, typically a Peripheral Component Interconnect Express (PCIe) bus, to a processor bus such as Industry Standard Architecture (ISA) or a System Management Bus (SMBus). With this bridge, the user has access to a system\'s processor bus resources such as its SRAM, ROM, Flash memory and I/O ports.

As a member of the programmable interconnect family of interconnect bridges, the PI7C9X794FCE bridges are used to provide users with an interface between a system\'s processor and peripheral buses. This bridge interconnect solution enables user\'s to easily create custom interconnect solutions that meet their specific requirements. It also provides users with a high-speed, low-power bus interconnect solution that allows them to easily move data between two incompatible bus levels without compromising performance.

The PI7C9X794FCE bridge can be used for two main purposes. Firstly, it can be used to provide a system\'s processor with access to a peripheral bus such as a PCIe or ISA bus, allowing it to access resources such as SRAM, ROM and I/O ports that are connected to these busses. Secondly, it can be used to facilitate the transfer of data between two different processors or buses by providing a high-speed and low-power data transport medium. This is accomplished by the bridge selecting the appropriate data flow direction and choosing the appropriate data protocol, such as PCI Express, ISA or SMBus.

The PI7C9X794FCE bridge also offers enhanced flexibility and scalability when connecting multiple devices. It supports up to 8 master and 8 slave devices, as well as support multiple communication protocols, such as PCIe, ISA and SMBus, which enables users to create a fully customizable interconnect solution. Additionally, the bridge\'s flexibility allows it to support wide range of endpoint devices including CPUs, FPGAs and other specialized ICs.

The PI7C9X794FCE bridge adopts a multi-layer architecture and features an on-board fabric that works in tandem with the bridge\'s control unit. The fabric can be used to provide a bridge with additional features such as enhanced data throughput, link error correction and low-power operation. Additionally, the fabric can help optimise the data path between the processor and peripheral busses.

The PI7C9X794FCE bridge also utilises a proprietary arbitration scheme to manage data request queues and deliver optimal data flow. This scheme helps to improve the bridge\'s throughput, latency and power efficiency by ensuring that the data is directed to its intended destination with minimal delay and no additional power consumption.

The PI7C9X794FCE bridge offers a wide range of applications, including system control and communications, specialised I/O, mobile applications and embedded platforms. In addition to the bridge\'s flexibility, the ability to customise the bridge\'s architecture to meet specific requirements makes the PI7C9X794FCE an ideal choice for a wide range of application segments.
