[Prof D. Gajski’s Y Chart, UCLA, Irvine CA]
C.Gebotys, Associate Professor, E&CE, May26, 2003

9. For example: Optimized Synthesis
6X code size improvements
1.6X performance improvements
87% improvements in
Memory bandwidth

10. Energy/Power Research for SoCs Modeling
1st to Model Dynamic Power
0.3-9% accuracy, VLIW Processor
Modeling Average Power,
<4% error, VLIW processor
C.Gebotys, Associate Professor, E&CE, May26, 2003

11. Experimental Verification
Bank analogous to aligned… same bank are aligned quad…
Bank, (o,1,2,3),
Same or different bank
Dual 0,1 bank I, quad 0-3 bank j
Bank, column versus cycles (analogous to DRAM’s.. But can have two addresses to one bank,
So better to use
Row(=addresses/4), column(=0-3)
