14. For a direct-mapped cache with a
32-bit address and 32-bit words, the following address bits are
used to access the cache.
Tag
Index
Offset
31-16
15-5
4-0
What is the cache block size (in words)?
How many blocks does the cache have?

1a) A memory unit has 28-bit address lines and 64-bit
input/output data lines. How many bytes of data can this memory
hold? How many words does it contain, and how large is each
word?
b) A memory unit consists of 32M words of 16-bit each. How many
bits wide address lines and input-output data lines are needed to
access this memory?
c) A memory unit consists of 512K bytes of data. How many bits
wide address lines are needed to...

5. Suppose we have a 32-bit computer with an instruction set
that supports immediate instructions as shown below:
Opcode Source Register Destination Register immediate
6 bits 5 bits 5 bits 16 bits
(a) How many registers at most does this computer have? (5%)
(b) How many operations at most can this computer have? (5%)
(c) What is the range of the number in the “immediate” field in
2'scomplement format? (5%)

Concern the following 16-bit floating point representation: The
first bit is the sign of the number (0 = +, 1 = -), the next nine
bits are the mantissa, the next bit is the sign of the exponent,
and the last five bits are the magnitude of the exponent. All
numbers are normalized, i.e. the first bit of the mantissa is one,
except for zero which is all zeros.
1. How many significant binary digits do numbers in this
representation...

This is a Discrete math problem.
a. How many bit strings of length 12 are there in total?
b. How many bit strings of length 12 contain an odd number of
1s?
c. How many bit strings of length 12 contain “111000” as a
substring of 6 consecutive bits in a row?

For a bit string containing 10 bits, how many strings are there
that contains 5 consecutive 0s or 1s.
The OR is inclusive in this example and it is AT LEAST 5
consecutive so 6 consecutive would still count.
I don't understand how I should approach this. There are too
many cases to exclude when calculating the permutation of a single
case.

A computer system has 16 processing registers R0,···,R15, where
each register has 32-bit storage capacity. The computer system uses
a common bus system for data transfer between registers, memory and
ALU. Answer the following questions if common bus is designed using
multiplexers
Size of each MUX needed for the design
Number of MUXs needed
Size of the bus (in bits)

SRAM with 4k words of 32 bits each. How many address bits are
needed to address these words?
1. Assuming that the central memory array has the same number of
rows as it has columns, how many rows are there?
2.How many of address bits are used by the row decoder
3.How many words are stored in each row
4. How many are used by column decoder

In a 16-bit little endian machine, how is the
text “YA” stored in a word? How is the integer number 910 stored in
a word? Write down the binary bits.
