Su Summary

• Dual to-host DMA descriptors transfer has been verified.
• DMA-0: 5 links of normal WIB data
• DMA-1: 5 links of hit finding data
• Central Router for hit finding data has been verified.
• AXI-Stream interface

§ Data unit: 32-bit § At least two 32-bit data between two valid data packages
