Q1Domain Verified
In a pipelined processor, what is the primary cause of a control hazard that requires the insertion of bubbles or stalls?
An instruction fetch from a slow memory device that misses the cache.
An arithmetic instruction that requires more than one clock cycle in the execution stage.
A branch instruction that changes the program counter before the fetch stage knows the outcome.
A data dependency where an instruction needs the result of a previous instruction that is not yet available.
Q2Domain Verified
When designing a memory-mapped I/O system for a microcontroller, what is a key hardware implication of placing a peripheral's register at memory address 0x20000000?
The CPU must use special I/O instructions, like IN and OUT, to access the peripheral.
The memory controller must route accesses to this address to the peripheral bus instead of the RAM.
The address 0x20000000 is reserved in the virtual memory page table for kernel-space access only.
The peripheral's register becomes cached, requiring explicit cache flushes for reliable communication.
Q3Domain Verified
A system uses a Harvard architecture instead of a Von Neumann architecture. What is a direct hardware consequence of this choice?
It eliminates the need for a Memory Management Unit (MMU) by using a fixed memory map.
It allows data to be executed as instructions, providing more programming flexibility.
It has a unified cache for both instructions and data, simplifying the memory hierarchy.
It requires separate buses and memory units for instructions and data.
