Advance Information
Functional Description
Features:
The FPI Bus is designed with the requirements of high-performance systems in mind.
The features are:
• Core independent
• Multimaster capability (up to 16 masters)
• Demultiplexed operation
• Clock synchronous
• Peak transfer rate of up to 800 Mbytes/sec (@ 100 MHz bus clock)
• Address and data bus scalable (address bus up to 32 bits, data bus up to 64 bits)
• 8-/16-/32- and 64-bit data transfers
• Broad range of transfer types from single to multiple data transfers
• Split transaction support for agents with long response time
• Burst transfer capability
• EMI and power consumption minimized
3.4.3 LFI
The LMB-to-FPI Interface (LFI) block provides the circuitry to interface (bridge) the FPI
bus and the Local Memory Bus (LMB).
LFI Features:
• Full support for bus transactions found within current TriCore™ 1.3 based systems:
– Single 8/16/32-bit Write/Read transfers from FPI to LMB
– Single 8/16/32/64-bit Write/Read transfers from LMB to FPI
– Read-Modify-Write transfers of 8/16/32-bit in both directions
– Burst transactions of 2, 4 or 8 data beats from the FPI to the LMB
– Burst transactions of 2 or 4 data beats from the LMB to the FPI
• Address decoding and translation as required by TriCore™ 1.3 implementation
• FPI master interface supports full pipelining on FPI bus
• LMB master interface supports pipelining on LMB within the scope of the LMB
specification
• FPI master interface can act as default master on FPI bus
• Programmable support for split LMB to FPI read transactions
• Retry generation on both FPI and LMB buses
• Full support for abort, retry, error and FPI timeout conditions
• Flexible LMB/FPI clock ratio support including dynamic clock switching support
• LFI core clock may be shut down when no transactions are being issued to LFI from
either bus and the LFI has no transactions in progress, thus saving power.
