SPI-4 Phase 1 Core V1.0
Product Brief
June 2001
Figure 2: SPI-4 Phase 1 Link Layer Application
On the system side, the SPI-4 Phase 1 core
interfaces to a single or to multiple links or
ports via Altera’s Atlantic interface.
The Spi4Tx block monitors the Source
FIFOs fill level and the flow control
information received from the opposite side
of the SPI-4 interface. If a Source FIFO has
data and the flow control information for the
corresponding channel indicates that it is
ready to accept data, the Spi4Tx block
initiates a data transfer from the Source
FIFO towards the SPI-4 interface.
The Spi4Rx block transmits the Sink FIFO
status information to the opposite side
according to the Sink FIFO almost-full flags.
The Spi4Rx block stores data received for a
particular link in that link’s FIFO. Sink FIFO
flags indicate to the user the presence of
data in the FIFO(s).
Gate Count
The SPI-4 Phase 1 Core configured for 4
channels and targeted to APEX II uses:
Logic Elements (LEs): 2700
Embedded System Blocks (ESBs): 23
The above numbers include the core and a
small amount of circuitry to implement a
loopback on the Atlantic Interface.
