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. DOWNLOAD.
