SUN Niagara 2 I/O power analysis:

|
total signal bits: 711
|
||
|
|
Total FBDIMM bits: (14+10)*2*8= 384
|
||
|
|
PCIe bits: (8 + 8)*2 = 32
|
||
|
|
10Gb NIC: (4*2+4*2)*2 = 32
|
||
|
|
Debug I/Os: 168
|
||
|
|
Other I/Os: 711- 32-32 - 384 - 168 = 95
|
||
|
|
|
||
|
|
According to "Implementation of an 8-Core, 64-Thread, Power-Efficient SPARC Server on a Chip"
|
||
|
|
90% of I/Os are SerDers (the calucaltion is 384+64/(711-168)=83% about the same as the 90% reported in the paper)
|
||
|
|
--> around 80Pins are common I/Os.
|
||
|
|
Common I/Os consumes 71mW/Gb/s according to Cadence ChipEstimate @65nm
|
||
|
|
Niagara 2 I/O clock is 1/4 of core clock. --> 87pin (<--((711-168)*17%)) * 71mW/Gb/s *0.25*1.4Ghz = 2.17W
|
||
|
|
|
||
|
|
Total dynamic power of FBDIMM, NIC, PCIe = 84*0.132 + 84*0.049*0.132 = 11.14 - 2.17 = 8.98
|
||
|
|
Further, if assuming I/O logic power is about 50% of I/Os then Total energy of FBDIMM, NIC, PCIe = 11.14 - 2.17*1.5 = 7.89
