10. Basic Architecture for a Single Unit Bus
The chapter explores the architecture of a single unit bus system within a CPU, detailing how data flows between registers, the ALU, and memory using control signals. It emphasizes the importance of synchronization and control units in managing data transfers and preventing contention on the bus. Furthermore, it illustrates the significance of read and write signals for effective communication between the CPU components and memory.

What we have learnt
- The architecture of a single unit bus involves a central bus connecting the CPU, memory, and I/O devices.
- Effective control signals are essential for preventing data contention on the bus.
- Data is transferred within the CPU using control signals that dictate read and write operations.
Key Concepts
- -- Single Bus Architecture
- A CPU architecture where a single bus is used to connect all components, allowing for data transfer between the CPU, memory, and I/O devices.
- -- Control Unit
- The component of the CPU that generates control signals to manage data transfers between registers and the bus, ensuring that only one data source outputs at a time.
- -- Multiplexer (MUX)
- A device that selects one of many input signals and forwards the selected input into a single line, often used in conjunction with the ALU for selecting operands.
- -- Data Contention
- A situation where two or more data sources attempt to output to the same destination at the same time, which can cause errors in data transfer.
- -- Microinstructions
- Simple instructions generated by the control unit that dictate specific actions within the CPU for data transfer and processing.
