1- Design and implement a 4-bit Arithmetic Logic Unit (ALU). The ALU takes two inputs; A and B, each one of them is a 4-bit number. The ALU operations are controlled by a set of selection inputs: I. L: is the mode input used to control the type of operation, L=0 for arithmetic operations and L=1 for logical operations. II. So and S1: are two inputs used for controlling the execution of specific operations. C, and Cout represent carry in and carry out, respectively. F represents the output containing the result of the operations. A block diagram of the ALU is shown in Fig.1. Co N A 4-Bit ALU V Cout B S1 So L Fig.1. Block diagram of ALU

فتح باستخدام مستدات Google L=0 (Arithmetic operations) L=1 (Logic operations) Si So Cout Operation Si So Cout Operation A>B X A AND B 1 A = B 1 X A OR B 1 A<B 1 X A XOR B A +1 1 X A NXOR B 1 A +B 1 1 A+B+1 1 1 A - B 1 1 1 B -A The result of the logic and arithmetic operations will be displayed on LEDS and 7 segment display. Since you are working with a 4-bit representation for 2's complement numbers, the maximum positive number is +7 and the most negative number is –8. A single seven-segment display can therefore be used to show the magnitude of the number. An LED will be used for indicating a “." sign for arithmetic operations, denoted S, in Fig.1. LEDS will also be used to indicate the status of ALU flags. 2- Implement the designed circuit using Logisim and test it for each of the following cases: a) (0011,0101) b) (0100,1001) c) (0010,0110) d) (0001, 1010)| Ili
