| What are the main issues associated with multiprocessor
caches and how might you solve them? | Intel | 1 |
| What is FPGA? | Intel | 2 |
| Are you familiar with VHDL and/or Verilog? | Intel | 4 |
| For a single computer processor computer system, what is the
purpose of a processor cache and describe its operation? | Intel | 1 |
| Explain Clock Skew? | Intel | 2 |
| Differences between DRAM and SRAM? | Intel | 4 |
| Suppose you have a combinational circuit between two
registers driven by a clock. What will you do if the delay
of the combinational circuit is greater than your clock
signal? (You can't resize the combinational circuit
transistors)
