How many operation selection lines are required for ALU which perform 32 operations?
Some of the data and control lines are shown with a slash and a number like 32. This indicates that the line is actually 32 lines in parallel, e.g. the result is 32-bits wide….1.9 Putting It All Together.
| c1 | c0 | Result |
|---|---|---|
| 0 | 1 | A OR B |
| 1 | 0 | A + B |
| 1 | 1 | A – B |
What is a 32-bit instruction?
A program written in machine language is a series of 32-bit numbers representing the instructions. Like other binary numbers, these instructions can be stored in memory. This is called the stored program concept, and it is a key reason why computers are so powerful.
What is 32-bit register?
One bit in the register can reference an individual byte in memory, so a 32-bit system can address a maximum of 4 GB (4,294,967,296 bytes) of RAM. The actual limit is often less than around 3.5 GB since part of the register is used to store other temporary values besides memory addresses.
What is a 32-bit ALU?
It is a combinational circuit taking two 32-bit data words A and B as inputs, and producing a 32-bit output Y by performing a specified arithmetic or logical function on the A and B inputs.
Which instruction are 32 bits long with extra 16 bits?
When 100 instructions are assumed, 20 instructions are 32-bit long. 16-bit long instructions and operands are executed within 32-bit. Therefore there are 40\% of the instructions. When 100 instructions are assumed, 40 instructions are 16-bit long.
How many numbers can 32 bits represent?
Integer, 32 Bit: Signed Integers ranging from -2,147,483,648 to +2,147,483,647. Integer, 32 Bit data type is the default for most numerical tags where variables have the potential for negative or positive values. Integer, 32 Bit BCD: Unsigned Binary Coded Decimal value ranging from 0 to +99999999.
How many different numbers can 32 bits represent?
Range for storing integers A 32-bit register can store 232 different values. The range of integer values that can be stored in 32 bits depends on the integer representation used.
How many arithmetic and logic operations are possible in a 4 bit ALU?
16 logic operations
The DM74LS181 is a 4-bit Arithmetic Logic Unit (ALU) which can perform all the possible 16 logic operations on two variables and a variety of arithmetic operations.

What is 16-bit and 32-bit processor?
While a 16-bit processor can simulate 32-bit arithmetic using double-precision operands, 32-bit processors are much more efficient. While 16-bit processors can use segment registers to access more than 64K elements of memory, this technique becomes awkward and slow if it must be used frequently.
What range of numbers can be represented by a 16-bit ALU?
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 the meaning of 16-bit and 32-bit processors?
How many 32-bit values does the ALU take in?
The ALU will take in two 32-bit values, and 2 control lines. Depending on the value of the control lines, the output will be the addition, subtraction, bitwise AND or bitwise OR of the inputs. Schematically, here is what we want to build:
How many control lines does the ALU take in?
Read each tutorial step carefully and complete the activities listed in each step. The ALU will take in two 32-bit values, and 2 control lines. Depending on the value of the control lines, the output will be the addition, subtraction, bitwise AND or bitwise OR of the inputs.
How many inputs and outputs does an Alu have?
The ALU has two 32-bit inputs (which we’ll call “A” and “B”) and produces one 32-bit output. We’ll start by designing each piece of the ALU as a separate circuit, each producing its own 32-bit output. Then we’ll combine these outputs into a single ALU result.
What is the function of Alu in computer?
ALU is the “calculator” portion of the computer. An arithmetic logic unit (ALU) is a major component of the central processing unit of the a computer system. It does all processes related to arithmetic and logic operations that need to be done on instruction words.
