Plans 2009/2010 Digital Readout Architecture FE-I3 bottleneck Both FE readout based on double column (DC) structureBoth FE readout based on double column (DC) structure FE-I4 local storage All hit pixels are shipped to EoC buffer. A hit pixel need to transfer its data to EoC before accepting new hit  congestion. Each pixel is logically independent inside the DC. Store data locally in DC until L1T. Only 0.25% of pixel hits are shipped to EoC  DC bus traffic “low”. Warning: Local Buffer Congestion??? Each pixel is tied to its neighbors -time info- (clustered nature of real hits). low traffic on DC bus 17 CPPM 9 June 2009 A.Rozanov
