Arithmetic logic unit
An arithmetic logic unit (ALU) is a combinational digital electronic circuit that performs arithmetic and bitwise operations on integer binary numbers.This is in contrast to a floating point unit (FPU), which operates on floating point numbers. An ALU is a fundamental building block of many types of computing circuits, including the central processing unit (CPU) of computers, FPUs, and ...DESIGN OF 16 BIT LOW POWER ALU DBGPU
Fig 7.Logic unit Fig 8. 4 bit logic unit Fig 9. 16bit logic unit 5. Shifter The ALU designed performs 7 Shift Rotate Operations namely arithmetic left shift(same as ...Week 2 Tutorial Building an ALU tuhs.org
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.Nibbler 4 Bit CPU | Big Mess o' Wires
Summary. Nibbler is a 4 bit CPU built from standard 7400 series logic chips – individual counters, registers, buffers, and gates. It’s an educational example of a simple CPU that’s easy to understand and build, but still capable of running games and other interesting programs.TMS320C54x DSP Functional Overview TI

I have written a Verilog code for a 4 bit Johnson counter which has the following states: 0000 0001 0011 0111 1111 1110 1100 1000 0000 .... and so onBranch predictor
In computer architecture, a branch predictor is a digital circuit that tries to guess which way a branch (e.g. an if–then–else structure) will go before this is known definitively.The purpose of the branch predictor is to improve the flow in the instruction pipeline.Branch predictors play a critical role in achieving high effective performance in many modern pipelined microprocessor ...Digital Counters Learn About Electronics
Four Bit Asynchronous Down Counter. To convert the up counter in Fig. 5.6.1 to count DOWN instead, is simply a matter of modifying the connections between the flip flops.8051 Microcontroller: block diagram and components
Introduction: What is a microcontroller? A complete computer system manufactured on a single chip is called a microcontroller. The features of a microcontroller are similar to that of a microprocessor like registers, ALU, program counter, flags, stack pointer, etc. Along with these common features, a microcontroller has some additional features such as a clock circuit, internal RAM, ROM ...
