What is a pointer in MIPS?
Pointer: a variable that contains the address of another variable. HLL version of machine language memory address.
How many bytes does it take to store all of the MIPS instructions of the above sequence in memory?
Instructions are all 32 bits. byte(8 bits), halfword (2 bytes), word (4 bytes)
How do you calculate MIPS?
- Divide the number of instructions by the execution time.
- Divide this number by 1 million to find the millions of instructions per second.
- Alternatively, divide the number of cycles per second (CPU) by the number of cycles per instruction (CPI) and then divide by 1 million to find the MIPS.
What is an immediate MIPS?
MIPS immediate addressing means that one operand is a constant within the instruction itself. The advantage of using it is that there is no need to have extra memory access to fetch the operand. But keep in mind that the operand is limited to 16 bits in size.
What is an immediate in assembly?
An immediate operand is a constant value or the result of a constant expression. The assembler encodes immediate values into the instruction at assembly time. If the source operand is immediate, the destination operand must be either a register or direct memory to provide a place to store the result of the operation.
What is the size of 1 word for MIPS?
32 bits
What is an immediate value?
An immediate value (or simply an immediate or imm) is a piece of data that is stored as part of the instruction itself instead of being in a memory location or a register. Immediate values are typically used in instructions that load a value or performs an arithmetic or a logical operation on a constant.
What is an immediate number?
order by. 5. In the area of machine code/instruction sets, an immediate value is a constant number embedded into the instruction itself , as opposed to one loaded from another place. For example, on x86: 6A 03 push 3. Here, 3 is an immediate because it’s included directly as part of the opcode (in the second byte).
What is an immediate addressing?
Register and immediate addressing means that the operand is either a register or specified as a constant within the assembly language instruction itself. In register addressing, an operand is fetched from, or written to, a register. For example: In this example, the 16-bit contents of DX are copied into AX.
What is the range of immediate operands that can be provided?
Immediate operands can be in the range of ±512.
What is the largest immediate possible in an addi instruction?
Immediate Operands The maximum value of an immediate operand varies among instructions, but it can never be greater than 232. The maximum size of an immediate on RISC architecture is much lower; for example, on the ARM architecture the maximum size of an immediate is 12 bits as the instruction size is fixed at 32 bits.
What does Andi do in MIPS?

How many unique values can a 16 bit immediate value hold?
A 16-bit integer can store 216 (or 65,536) distinct values. In an unsigned representation, these values are the integers between 0 and 65,535; using two’s complement, possible values range from −32,768 to 32,767.
What is a group of 16 bits called?
In computing, a hextet is a sixteen-bit aggregation, or four nibbles. As a nibble typically is notated in hexadecimal format, a hextet consists of 4 hexadecimal digits. A hextet is the unofficial name for each of the 8 blocks in an IPv6 address.
What is the maximum decimal number can a 16 bit binary digit can represent?
65535
What is the largest 16 bit binary number that can be represented with?
1
How many numbers can be represented with 6 bits?
For example, a string of three bits can represent up to eight distinct values as illustrated in Table 1….Binary number representation.
| Length of bit string (b) | Number of possible values (N) |
|---|---|
| 6 | 64 |
| 7 | 128 |
| 8 | 256 |
| 9 | 512 |
What is largest binary number that can be expressed with 10 bits?
1024
What is the largest binary number that can be expressed with 14 bit?
The largest binary number you can represent in 14 bits, assuming no sign bit, is 1111, that’s 2¹⁴ – 1 or 16,383.
How many total numbers can be represented with an 8 bit binary base 2 system?
We have also seen previously that an 8-bit binary number (a byte) can have a value ranging from 0 (sub>2) to 255 (sub>2), that is 28 = 256 different combinations of bits forming a single 8-bit byte. So for example an unsigned binary number such as: sub>2 = 64 + 8 + 4 + 1 = 7710 in decimal.
What is the largest binary number in 8 bits?
256
What is the largest base ten number that can be represented with 3 bytes in binary?
111
How many things can 4 bits represent?
16
How do you write 7 in binary?
Convert 0.100 1001 to decimal. Take the binary number 0100 1001 (=7310), and divide by 27=128….

How A is written in binary?
Well, computers don’t use the letter A. They use the eight character binary number to represent A.
