Question

Give the bit pattern for the instruction LDWX 0x0124,x (pep9)

Answer #1

First 8 bits for LDA instruction will be 1100 raaa.

from
them,

First 4 bits,

Instruction specifier for LDA instruction is
**1100**.

For
5th bit,

if it is accumulator then 1 and if index register then 0.

Here index register X is used. So, r = 1 means 5th bit will be
**1**.

Other 3 bits(6, 7 and 8) represents addressing mode. x from given
instruction specifies Indexed addressing mode.

For index addressing aaa = **101**.

Thus,

Fisrt 8 bits will be 1100 1101

Here
hexadecimal constant is 0124. Thus other bits are **0000 0001
0010 0100**.

Thus,
final bit pattern for LDWX 0x0124, x will be

**1100 1101 0000 0001
0010 0100.**

Give the bit pattern for the instruction LDWX 0x54C1,d
that instruction is in Assembly Language

1. Give the bit pattern for the instruction STWX 0x4C1A,d

Please convert the following bit pattern to a MIPS
instruction.
0000 0001 0110 0110 0100 1000 0010 0000
1000 1101 1001 1010 0000 0000 0001 1100

14.5. Give the name
of the bit, the name of the register that it is in, the register's
address, which bit, and the default or reset state of the bit for
each of the following:
a-What bit indicates that the timer has overflowed?
b-What bit enables the timer overflow interrupts?
c-What bits are used to prescale the timer clock?

Suppose the opcode of an MIPS instruction is 0 in decimal, the
funct is 011000 in binary, and the rest of the machine code is
c4000 in hexadecimal (from high-order bit to low-order bit). What
is the instruction? When showing the registers, use names (e.g.
$t0, $s2) instead of indices (e.g $8, $17).

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%)

Create a FSM that detects the input bit pattern ‘01’. The output
will be ‘0’ until the exact pattern ‘01’ is received. At the point
of receiving ‘01’, the FSM will output 1, and then go back to
output ‘0’ until the next ‘01’ is received.
1) Draw the Moore FSM diagram for the above
2) Write the FSM tables:
a. State Assignment (Gray Encoding)
b. State Output
c. State Transition Tables
3) Simplify the Output logic (use K-Map if...

Explain how program evaluation can contribute to the
improvement of curriculum and instruction.
please give an example as well as a
reference.

Instruction: Describe the method of establishing and evaluating for
a triple integral. Give an example using one of the following
options: (a) triple iterated integral, (b) use of spherical
coordinates, (c) use of cylindrical coordinates.

You are designing an instruction set for an embedded system and
have decided to use a 16-bit representation for integers and
ﬂoating point numbers.
What is the 16-bit binary representation (in hexadecimal using
lower-case letters, e.g., 0x39ab) of -13 (base 10) when represented
as a two’s complement integer?
