Full solved answer →Basic computer instruction format and register organization
What is Instruction Format of basic computer architecture? A computer uses a memory unit with 256K words of 32 bits each. Draw the instruction word format and indicate the number of bits in each part. [5]
An instruction format specifies the layout of bits within an instruction word. It defines how the total bits of the word are partitioned into fields, typically: - Mode field (I): indicates the addressing mode (direct or indirect). - Operation code (opcode):...
Full solved answer →Explain the instruction format of basic computer. Differentiate between RISC and CISC computer.[10]
Note: The reference notes were not available for this topic. The answer below is based on standard computer organization and architecture curriculum as taught in TU BSc CSIT. --- An instruction format defines the layout of bits in a machine instruction. It ...
Full solved answer →Explain the register organization of basic computer. [5]
The basic computer (as described in the classic Morris Mano model) uses a set of registers to hold temporary data, addresses, and control information during program execution. The register organization defines the internal structure of the CPU. --- The basi...
Full solved answer →SAP 1 computer components and block diagram
Explain the components of SAP 1 computer with its block diagram. How is it different from SAP 2 computer?[10]
SAP (Simple As Possible) is a simplified educational computer architecture introduced by Albert Paul Malvino to help students understand the fundamental operation of a digital computer, including the fetch, decode, and execute cycle. SAP-1 is the most basic...
