RT54SX32S

CorePCI connects I/O, memory, and processor subsystem resources to the main system via the PCI bus. CorePCI RT54SX32S  is intended for use with a wide variety of peripherals where high-performance data transactions are required.Figure 1 on page 2 depicts typical system applications using the baseline IP core. While CorePCI RT54SX32S  can handle any transfer rate, most applications will operate at zero wait states. When required, wait states can automatically be inserted by a slower peripheral.

The core RT54SX32S  consists of up to four basic units: the Target controller, the Master controller, the backend, and the wrapper. Both the Target and Master controllers remain constant for a variety of backends. A backend controller provides the necessary control for the I/O or memory subsystem and interfaces to the Target controller through a generic interface. The wrapper combines the Target and Master blocks with the backend for implementation in a single Actel device.

CorePCI RT54SX32S  can be customized in two different ways. First, a variety of variables are provided to easily change parameters such as memory and I/O sizes. The second method is to develop user-specific backend controllers for non-standard peripherals.
