The arithmetic logic unit and position scaler receives information from a data bus, provides arithmetic functions such as add, logical AND and exclusive OR, and shift manipulations to the information received from the data bus, and then directs the resultant information to the same data bus. The...
Logical Shift ALeft Logical Shiftof one position moves each bit to the left by one. The vacant least significant bit (LSB) is filled with zero and the most significant bit (MSB) is discarded. ARight Logical Shiftof one position moves each bit to the right by one. The least significant ...
The Bit Shift block performs a logical or arithmetic shift on the input signal. This block is different from the Shift Arithmetic block in terms of simulation and HDL code generation behavior. The Bit Shift block can perform logical shifting of a signed number without having to perform a reinte...

An 'Arithmetic Instruction' refers to a set of operations executed by the Arithmetic Logic Unit (ALU) of a processor, including binary, decimal, logical, shift/rotate, and bit/byte manipulation instructions for performing arithmetic computations on different data types. ...
A shift to the right can be classified either as a logical shift right or an arithmetic shift right. For a logical shift right, a 0 is incorporated into the most significant bit for each bit shift. For an arithmetic shift right, the most significant bit is recycled for each bit shift. ...

There is no difference between logical and arithmetic left shifts. load: Loads shift register with data[63:0] instead of shifting. ena: Chooses whether to shift. amount: Chooses which direction and how much to shift. 2'b00: shift left by 1 bit. 2'b01: shift left by 8 bits. 2'b10:...
has a first mode of operation and a second mode of operation. In the first mode of operation, the address generation unit can selectively generate a memory address. In the second mode of operation, the address generation unit can selectively execute arithmetic instructions and logical instructions....
