please help question no 7-10 thankyou

7. Draw the PAL block diagram and FPGA architecture. (10%) 8. What is the average time to read or write a 512 Byte sector for a typical disk rotating at 3000 rpm? The advertised average seek time is 20ms, the transfer rate is 2MB/s and the controller overhead is 2ms. Assume that the disk is idle so that there is no waiting time. (10%) 9. Assume that a disk has the following characteristics: Track size: 10,000 bytes Rotational speed: 10 ms/revolution Block size: 1,000 bytes What is the maximum transfer rate per track for this disk? (Measured in bits per second) (10%) 10. A slice from a Virtex FPGA is shown in the following Figure. Show how one or more of these slices can be configured to produce the SOP function: A, AA, A+ A,A,A, A+B B.B.B.+B,B.B.B. (10%) MUX LUT MUX LUT Slice
