The figure below shows an address decoder used to select between
four memory mapped components connected to a microprocessor with a
24-bit address bus.
What is the size of the processor address space? (Justify your
answer.)

you answer for this question but very shortcut can you please
answer with some nots thanks
. Provide this 8-bit CPU with a 64Kb yte memory space by making use of 16K x 4 memory chip like the ones provided in the figure below. ) Fill in the blanks beside and inside the memory chips with the appropriate numbers. The number on top of this The spaces besides the A's and the D's are to indicate which lines of the...
Problem-Part (a): (506) How many 32x2 memory chips (in addition to one 64x8 chip) do we need to construct the PROM of 128 bytes? Show how you get it? Problem-Part (b): (5%) How many 32x4 memory chips do we need to construct the RAM of 96 bytes? Show how you get it? Problem-Part (c): (10%) Show the memory address range (i.e., the first address and the last address) for the 64x8 PROM chip? Show how you get it? Problem-Part (d):...
Consider a logical address space of 8 pages; each page is 2048 byte long, mapped onto a physical memory of 64 frames.(i) How many bits are there in the logical address and how many bits are there in the physical address?(ii) A 6284 bytes program is to be loaded in some of the available frames ={10,8,40,25,3, 15,56,18,12,35} . Show the contents of the program's page table.(iii) What is the size of the internal fragmentation?(iv) Convert the following logical addresses 2249...
3. (6 pts) Consider a new processor. The memory system is 32-bit byte- addressable. The on-chip cache memory is 128 KByte 4-way set-associative, with a 64 byte block size. (a) Draw a diagram showing how the cache controller will split the memory address: for each field. show its name and number of bits. (b) The design team decided to change the cache architecture to a direct mapped one. For each of the parameters in the following table, indicate the impact...
Design a Partial address decoded memory containing – 4 Chips – Each chip contains 8K x 8 bits – You are to use 20 address lines
(a) Clearly draw a memory chip of size 512 × 8 and the associated decoder inside it, with all address bus and data bus (with bus width) clearly depicted. (b) how many such memory chips are needed to compose a memory of 2k×32? Draw a block diagram of these chips with all vital bus and wires and additional necessary logic specified.
