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.

Term: Single Bus Architecture
Definition: 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.
Term: Control Unit
Definition: 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.
Term: Multiplexer (MUX)
Definition: 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.
Term: Data Contention
Definition: 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.
Term: Microinstructions
Definition: Simple instructions generated by the control unit that dictate specific actions within the CPU for data transfer and processing.
