The following is the summary of my work in the week of Oct 2 - Oct 9. 1. Give a presentation on stacked power supply with Sasank on our group meeting. 2. Answer the questions coming from Intel on the stacked power supply paper. 3. Prepare the first home work assignment for EE209A and worked out a program to implement the dynamic programming algorithm to solve the non-slicing floorplanning problem. 4. Under the same setting as we presented in the FPGA 2006 paper, obtain the power efficiency of stacked power supply by linear regulators. This can be used to answer Vivik's question on the comparison between linear regulator and 2-level stacked power supply.
