1. What is the difference between DRAM and SRAM, in terms of characteristics such as speed, size and cost? 2. List and briefly define three techniques for performing I/O (i.e., communicating between the processor and I/O devices). 3. What is the difference between memory-mapped I/O and the Isolated I/O (i.e., I/O Addressing Independent of Memory)? 4. When an interrupt occurs, how does the processor identifies which device issued the interrupt? 5. When a DMA module takes control of a bus, and while it retains control of the bus, what does the processor do? Homework Assignment #5 Dr. Hatfield 6. What is the minimal address bits for a 512MB memory? What about a 24GB memory? 7. Provide a short description and definition for each of the following non-volatile memory technologies Drum memory Magnetic core memory Bubble memory Flash memory Static RAM (SRAM) Dynamic RAM (DRAM) Synchronous DRAM (SDRAM) Cache DRAM (CDRAM) RamBus DRAM (RDRAM) DDR SDRAM PRAM RRAM Millipede 8. The input status bit in an interface circuit, which indicates that new data are available, is cleared as soon as the input data register is read. Why is this important?
