Final answer:
The hardware loaded TLB handles a miss by initiating a memory request, while the software loaded TLB requires the operating system to handle the miss by retrieving the translation from memory.
Step-by-step explanation:
When a miss occurs on a hardware loaded Translation Lookaside Buffer (TLB), the processor initiates a request to the memory system to retrieve the necessary translation. This request is typically handled by dedicated hardware components, such as a memory management unit (MMU) or cache controller.
On the other hand, in a software loaded TLB, when a miss occurs, the operating system is responsible for handling the miss. The operating system retrieves the necessary translation from the page table stored in main memory and updates the TLB with the new entry.
For example, let's consider a hardware loaded TLB. If a miss occurs, the MMU would generate a memory request to retrieve the translation from memory. Once the translation is obtained, it is stored in the TLB for future use, improving performance by eliminating the need to access memory for subsequent translations.
