Logic diagram of 1 bit alu

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 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 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. Features 2 TMS320C54x DSP Functional Overview 1.1 Features Table 1–1 provides an overview the TMS320C54x, TMS320LC54x, and TMS320VC54x fixed-point, … 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 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 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 on International Journal of Ethics in Engineering & Management Education Website: www.ijeee.in (ISSN: 2348-4748, Volume 1, Issue 4, April 2014) MIPS BASED 64-BIT RISC CPU Khandhoba B R Geeta patil Asst.Professor.Dept.of ECE Asst.Professor.Dept.of ECE BKEC Basavakalyan BKEC Basavakalyan [email protected] [email protected] Abstract: The main aim of the project is simulation and … International Journal of Computer Applications (0975 – 8887) Volume 73– No.14, July 2013 A
