Question 6 Soalan 61 (iii) one stage of 1-bit ALU. satu peringkat litar aritmetik 2-bit. (3 Marks / Markah) (a) (iv) The arithmetic logic unit (ALU) represents the fundamental building block of the central processing unit (CPU) of a computer. Illustrate the composition of an ALU in a block diagram. Unit Aritmetik Logik (ALU) mewakili blok bangunan asas bagi unit pemprosesan posat (CPU) komputer. Thestrasikan komposisi ALU dalam satu gambarajah blok.) 3-bit ALU by cascading the block diagram of 1-bit ALU. LALU 3-bit dengan melatakan ALU 1-bit.) (4 Marks / Markah) (3 Marks / Markah) (b) An ALU consist of an arithmetic and logic function tables as in Table 6.1 and Table 6.2. Based on the tables, construct the following: Suat ALU terdiri daripada jadal fungsi logik dar aritmetik seperti dalam Jadual 61 den Jadual 6.2. Berdasarkan jadual-jadwal tersebut, binakan yang berikut: Table 6.1 Jadual 6.11 Cin-1 F Si 0 0 |1 | 1 SO 0 1 | 0 1 Cin=0 F = A+B F = B (transfer) = B (complernent) F = A+B = A + B + 1 (subtract B-A) F = B + 1 (increment) F = B + 1 (negate) F = A + B + 1 (subtract) F Table 6.2 Jadwal 6.21 si so Output Operation 0 0 F = A NOT 01 F = A- BAND 1 0 F = AB OR 11 F = A B XOR 1) one stage of 1-bit arithmetic circuit.
