What would the layouts be in 32-bit machines? 7.19 A certain two-way set-associative cache has an access time of 4 ns, compared to a miss time of 60 ns. Without the cache, main memory access time was 50 ns. Running a set of bench-marks with and without the cache indicated a speedup of 90%. What is the approximate...

A (word, bit, block, byte) or (Sector, cache line, page, row) is the unit of data transferred between cache, memory and the processor. A common size for a block is (64, 16, 32, 4k, 512) (bytes, lines, words, bits)

Explain how a 32-bit byte memory address should be divided into
Tag/Index/Offset fields for each of the cache configurations below.
Note: 1KB = 210 bytes. You must explain how many bits to assign to
each field and the ordering of the three fields. You get at most
50% of the credit if you give the length of each field without an

The RISC-V 32-bit architecture supports virtual memory with 32-bit virtual addresses mapping to 32-bit physical addresses. The page size is 4Kbytes, and page table entries (PTEs) are 4 bytes each. Translation is performed using a 2-level page table structure. Bits 31:22 of a virtual address index the first-level page table. If the selected first-level PTE is valid, it points to a second-level page table. Bits 21:12 of the virtual address then index that second-level page table. If the selected second-level...

Given a direct-mapped cache that will contain 32,768 bytes of data and four-word blocks (where each word is 4 bytes) and assuming 32-bit addressing; How many additional bits are required for the overhead associated with the 32,768 bytes of data? What is the overhead (additional space required) for the 32,768 bytes of data, expressed as a percentage?
