DESCRIPTION

The IDT88P8341 is a SPI (System Packet Interface) Exchange with a SPI-

3 interface and a SPI-4 interface. The data that enter on the low speed interface

(SPI-3) are mapped to logical identifiers (LIDs) and enqueued for transmission

over the high speed interface (SPI-4). The data that enter on the high speed

interface (SPI-4) are mapped to logical identifiers (LIDs) and enqueued for

transmission over the low speed interface (SPI-3). A data flow between SPI-

3 and SPI-4 interfaces is accomplished with LID maps. The logical port

addresses and number of entries in the LID maps may be dynamically

configured. Various parameters of a data flow may be configured by the user

such as buffer memory size and watermarks. In a typical application, the

IDT88P8341 enables connection of a SPI-3 device to a SPI-4 network

processor. In other applications a SPI-4 device may be connected to a SPI-3

network processor or traffic manager.
