- 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?AssemblyWhat does "align 8,5" mean? Draw the data memory layout of the data memory starts at 0x20000000Area myData, DataAlign 4a DCB 1b DCB 2c DCB 3Align 8,5d DCB 5Question)E Explain a XYZ method of transferring data from the computer's RAM to another part of the computer without processing it using the CPU. As a sound card may need to access data stored in the computer's RAM, but since it can process the data itself, XYZ is a means of having a peripheral device control a processor's memory bus directly. It permits the peripheral, such as a UART, to transfer data directly to or from memory without having each byte (or wordhandled by the processor. Draw a diagram of the unit used in XYZ and how data is transferredusing this method.

- Please explain how prioritizing the I/O queue above the process execution queue might improve performance. If the I/O is interrupted, who knows what will happen. To what extent this will reduce the maximum burst rate of the CPU is unclear. I don't think I understand what you're getting at.please explain these bullets more In memory-mapped I/O devices and main memory share the same address space. ⚬Each I/O device has its own reserved block of memory. ⚬Memory-mapped I/O therefore looks just like a memory access from the point of view of the CPU. ⚬Thus, the same instructions to move data to and from both I/O and memory, greatly simplifying system design. In small systems the low-level details of the data transfers are offloaded to the I/O controllers built into the I/O devices.Suppose a computer using fully associative cache has 224 bytes of byte-addressable main memory and a cache of 128 blocks, where each cache block contains 64 bytes.Q.) What is the format of a memory address as seen by the cache; that is, what are the sizes of the tag and offset fields?
