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 - Add block header and chunk trailer Test data generator has been developed for test purpose. • - Can be e rep eplaced ed by Hit Finding or or Hit Finding Emulator or A simplified ed FW has been een built and tes ested ed. • - Only with PCIe interface - Registers read and write via fpep epo 6
