DESCRIPTION

The IDT88P8344 is a SPI (System Packet Interface) Exchange with four SPI-

3 interfaces and one 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 a 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

IDT88P8344 enables connection of multiple SPI-3 devices to a SPI-4 network

processor. In other applications SPI-3 or SPI-4 devices may be connected to

multiple SPI-3 network processors or traffic managers.
