7.1.1.6 ii_quixote_dsp_emif_b

Supported Platforms: Quixote

Description:

This component is the interface between the Quixote application logic DSP EMIF B bus. The

Quixote uses DSP EMIF B primarily to communicate with the PCI streaming controller via a 32K

bi-directional FIFO.

The DSP EMIF B interface component has two primary functions: a interface to the PCI streaming

FIFOs and an lower speed interface to the PCI bus controller. The interface to the PCI streaming

FIFOs provides a high speed, 100 MHz data path to the devices. The lower speed control bus to

the PCI streaming controller provides a half-speed bus interface to the controller.
