- If a microprocessor has a cycle time of 0.5 nanoseconds, what’s the processor clock rate? If the fetch cycle is 40% of the processor cycle time, what memory access speed is required to implement load operations with zero wait states and load operations with two wait states?Most Intel CPUs use the __________, in which each memory address is represented by two integers.A main memory unit with a capacity of 4 megabytes is built using 1Mx 1-bit DRAM chips.Each DRAM chip has 1K rows of cells with 1K Cells in each row. The time taken for a single refresh operation is 100 nanoseconds. The time required to perform one refresh operation on all the cells in the memory unit?
- S I32-bit wide main memory unit with a capacity of 1 GB is built using 256M x 4 - bit DRAM chips The number of rows of 1memory cells in the DRAM chip is 2 The time taken to perform one refresh operation is 50 nanoseconds, The refresh period is 2 milliseconds. The percentageIn 8Gi x 32 RAM chip, 8Gi represents the total number of unique addressable memory locations. True FalseA CPU is equipped with a cache. If it takes 4 ns to access the data from the cache and 100 ns to access data from the main memory, what is the effective memory access time if the hit ratio is 90%? Answer = ns
