Fill in the blanks to submit your answer to the following questions: (a) The lowest memory address associated with the 512KB RAM is .Write the complete 20-bit address in HEXADECIMAL notation without spaces. Note: For example, the lowest memory address associated with the RESERVED region is 0x00000 in HEXADECIMAL notation. (b) The highest memory address associated with the 512KB RAM is .Write the complete 20-bit address in HEXADECIMAL notation without (c) The memory-mapped 10 address of the 1B Keyboard register is .Write the complete 20-bit address in HEXADECIMAL notation without (d) Say we utilize a DMUXBWay to route the load signal to the various regions of the memory in order to perform a data write. What would be the binary values of the DMUXBWay select bits needed in order to perform data write to SCREEN? Note: For example, if the select bits 2:0 were 011 then you'd write Ob011 or 011

Given a computer equipped with 67,108,864 bytes of memory with 16-bit cells, how many bits are needed to specify a memory address?
I have this problem from my textbook that I do not understand, despite re-reading the section on segmentation and paging. "The IBM system/370 architecture uses a two-level memory structure and refers to the two levels as segments and pages, although the segmentation approach lacks many of the features described in Chapter 8. For the basic 370 architecture, the page size may be either 2 KB or 4 KB, and the segment size is fixed at either 64 KB or 1 MB. For the 370/XA and 370/ESA architectures, the page size is 4 KB and the segment size is 1 MB. What advantages of segmentation does this scheme lack? What is the benefit of segmentation for the 370?"Can you help me undertand what they are looking for in this explanation?
1. How many bits are required to address a 8M × 16 main memory if a) Main memory is byte-addressable? b) Main memory is word-addressable?
All microprocessors have same number of address lines but different number of data lines. Select one: True False
2. A memory location has a logical address where the segment address is the first four digits is your roll number and the offset address is the last four digits of your roll number. Find the physical address of the memory location. [example: if your roll number is 1234200516789, then the segment address is 1234h and the offset address is 6789h]
The CPU employs values to enter memory places, and certain registers save both instruction and data addresses. Using the above statement as a reference, enumerate all of the registers involved in the aforementioned operations.
Show how the decimal value 2019111310 would be stored by byte-addressable machines with 32-bit words, using little endian format and then big endian format. Assume the value starts at address 201916. Draw a diagram of memory and place the appropriate values in the correct (and labeled) memory locations.
Suppose a computer using direct mapped cache has 224 bytes of byte- addressable main memory and a cache size of 64K bytes, and each cache block contains 32 bytes. (Note: 64K = 26 * 210) a) How many blocks of main memory are there? b) What is the format of a memory address as seen by cache, i.e., what are the sizes of the tag, block, and offset fields?
5. The ending address of a memory of size 1KB is 33FFH, then what is the starting address of the memory.
18. A computer memory has an address bus that is 12 bits wide. What is the maximum number of memory registers that can be accessed over that bus. Provide your answer in hexadecimal.
