Previous Question: An 8KB direct mapped write-back cache is organized as multiple blocks, each of size 32-bytes. The processor generates 32-bit addresses. The cache controller maintains the tag information for each cache block comprising of the following. 1 Valid bit 1 Modified bit As many bits as the minimum needed to identify the memory block mapped in the cache. What is the total size of memory needed at the cache controller to store metadata (tags) for the cache? option (A) 4864 bits (B) 6144 bits (C) 6656 bits (D) 5376 bits Next Question: On a non-pipe lined sequential processor, a program segment, which is a part of the interrupt service routine, is given to transfer 500 bytes from an I/O device to memory. Initialize the address register Initialize the count to 500 LOOP: Load a byte from device Store in memory at address given by address register Increment the address register Decrement the count If count != 0 go to LOOP Assume that each statement in this program is equivalent to a machine instruction which takes one clock cycle to execute if it is a non-load/store instruction. The load-store instructions take two clock cycles to execute. The designer of the system also has an alternate approach of using the DMA controller to implement the same transfer. The DMA controller requires 20 clock cycles for initialization and other overheads. Each DMA transfer cycle takes two clock cycles to transfer one byte of data from the device to the memory. What is the approximate speedup when the DMA controller based design is used in place of the interrupt driven program based input-output? option (A) 3.4 (B) 4.4 (C) 5.1 (D) 6.7

An application loads 100 libraries at startup. Loading each library requires exactly
one disk access. The seek time of the disk to a random location is given as 10ms.
Rotational speed of disk is 6000rpm. If all 100 libraries are loaded from random
locations on the disk, how long does it take to load all libraries? (The time to
transfer data from the disk block once the head has been positioned at the start
of the block may be neglected)

option
(A) 0.50s
(B) 1.50s
(C) 1.25s
