RISC Microcode from RAM
C.3.2 Performance
At 25 Mhz, an aggregate ATOM1 bandwidth of 10 Mbps divided among the 4 SCCs con-
sumes 100% of the processing power of the RISC communications engine. If only a percent-
age of the total available ATOM1 bandwidth is used, the remaining RISC processing power
can be used to run other protocols on other channels. Table C-3 shows the possible QUICC
configuration.
C-5
• Empty cells transmitted when there are no pending data transfers.
• Empty cells and cells with non-matching headers are automatically discarded on re-
• Scrambling option is provided utilizing the self-synchronizing X
• Incoming cells with incorrect HECs are received and marked.
• Bandwidth reservation mechanism in the transmitter to allow mixing of data and isoch-
• CAM support on reception for handling many connections.
