Chapter 3, Problem 5PE
Program Plan Intro

IEEE binary32 format:

The diagrammatic representation for IEEE binary32 format is given below:

Systems Architecture, Chapter 3, Problem 5PE

This format contains three fields such as sign bit, exponent and mantissa.

  • Sign bit: This bit contains 1 bit. Here, “0” denotes positive number and “1” denotes negative number.
  • Exponent:
    • The exponent field contains “8” bits.
    • This field required to denote both positive and negative exponents.
    • The value of exponent is computed by adding a bias with actual exponent. That is, “value of exponent = actual exponent + bias”.
  • Mantissa:
    • This field contains “23” bits.
    • It is a part of a value in scientific notation or a floating-point number, containing significant digits.

Create 6 users: Don, Liz, Shamir, Jose, Kate, and Sal. Create 2 groups: marketing and research. Add Shamir, Jose, and Kate to the marketing group. Add Don, Liz, and Sal to the research group. Create a shared directory for each group. Create two files to put into each directory: spreadsheetJanuary.txt meetingNotes.txt Assign access permissions to the directories:  Groups should have Read+Write access Leave owner permissions as they are  “Everyone else” should not have any access   Submit for grade: Screenshot of  /etc/passwd contents showing your new users Screenshot of /etc/group contents showing new groups with their members Screenshot of shared directories you created with files and permissions
⚫ your circuit diagrams for your basic bricks, such as AND, OR, XOR gates and 1 bit multiplexers, ⚫ your circuit diagrams for your extended full adder, designed in Section 1 and ⚫ your circuit diagrams for your 8-bit arithmetical-logical unit, designed in Section 2. 1 An Extended Full Adder In this Section, we are going to design an extended full adder circuit (EFA). That EFA takes 6 one bit inputs: aj, bj, Cin, Tin, t₁ and to. Depending on the four possible combinations of values on t₁ and to, the EFA produces 3 one bit outputs: sj, Cout and rout. The EFA can be specified in principle by a truth table with 26 = 64 entries and 3 outputs. However, as the EFA ignores certain inputs in certain cases, it is easier to work with the following overview specification, depending only on t₁ and to in the first place: t₁ to Description 00 Output Relationship Ignored Inputs Addition Mode 2 Coutsjaj + bj + Cin, Tout= 0 Tin 0 1 Shift Left Mode Sj = Cin, Cout=bj, rout = 0 rin, aj 10 1 1 Shift Right…
