Table 1 Four signal groups
From: Energy saving for OpenFlow switch on the NetFPGA platform based on queue engineering
Signal groups | Function |
|---|---|
work_udp_grp0 = udp_in_wr| vlan_remover_out_wr| (!opl_in_fifo_empty); | Report UDP is processing and forwarding packets. |
work_udp_grp1 = vlan_adder_out_wr | udp_out_wr; | |
work_cputx_grp = cpu_q_dma_wr_pkt_vld | cpu_q_dma_wr; | Report NF2 DMA is sending data to CPU DMA Queue. |
work_cpurx_grp = cpu_q_dma_pkt_avail | cpu_q_dma_rd_rdy; | Report CPU Queue is receiving packets. |
