My Diploma Thesis
Development of an SCI bridge for coupling PCI-based PCs
In this work a PCI-to-SCI bridge was developed. The hardware consists of
an PCI interface chip, two FPGAs from Xilinx, 32kByte Dual Ported RAM,
and the Dolphin Link Controller (for the SCI coupling). The behavior of
both FPGAs was described in VHDL and then synthesized to 'real' Hardware.
The FPGAs connect the local Bus and the LinkController's bus (B-Link),
and perform protocol conversions for both directions. The transaction management
has 32kByte buffer memory for incoming and outgoing packets. To translate
to the global address space, an address translation mechanism is used for
outgoing packets. Furthermore, LOCK and DMA accesses are supported. There's
also an interface to an external communications monitor, that is currently
developed.
The work is finished, the german version of the thesis can be downloaded.
