Study Notes
Registers in Computer Systems
- A MAR (Memory Address Register) holds the memory address of data that is to be written to or read from memory.
- A PC (Program Counter) holds the memory address of the next instruction to be fetched.
Loading of Registers
- Registers are typically loaded in parallel, where all bits of the register are loaded simultaneously.
- Parallel loading is used when a register needs to be loaded with a data value, such as when an input value is being loaded into a register.
Clock Generator
- A master clock generator produces a timing signal that synchronizes the operations of the digital system.
Register Operations
- Input values in a register get loaded when a clock pulse is applied, and the register is enabled to load.
- A micro operation is a basic operation that can be performed on a register, such as loading, storing, or shifting.
Register Transfer Language
- The transfer of information from one register to another is represented in Register Transfer Language (RTL) using an arrow symbol, e.g., R1 → R2.
- An n-bit register consists of n flip-flops, each capable of storing a 0 or a 1.
Register Transfer
- A hardware capability necessary for a register transfer to occur is a set of wires, known as a bus, that interconnects the registers.
Register Notation
- Computer registers are typically denoted by a letter, such as R, followed by a number, e.g., R1, R2, etc.
Sequencing Microoperations
- The symbolic notation used to specify the sequence of microoperations is called a microprogram.

Description
Explore the concept of micro operations, which are elementary operations performed on data stored in registers, such as shift, count, clear, and load. Learn about register transfer language, a symbolic notation used to specify the sequence of microoperations.
