Why does machine cycle need to have pipelining?

Why does machine cycle need to have pipelining?

Pipelining improves the throughput of the system. 2. In every clock cycle, a new instruction finishes its execution. The more pipeline stages a processor has, the more instructions it can process “at once” and the less of a delay there is between completed instructions.

What are the various types of pipeline conflicts in instruction pipeline?

Pipeline Conflicts

• Timing Variations. All stages cannot take same amount of time.
• Data Hazards. When several instructions are in partial execution, and if they reference same data then the problem arises.
• Branching.
• Interrupts.
• Data Dependency.

Which of the following microprocessor has two pipelines?

The Atmel AVR and the PIC microcontroller each have a two-stage pipeline.

What is meant by instruction pipelining?

Instruction pipelining is a technique used in the design of modern microprocessors, microcontrollers and CPUs to increase their instruction throughput (the number of instructions that can be executed in a unit of time). The CPU consists internally of logic and memory (flip flops).

What is the difference between pipelining and sequential processing?

In sequential mode, data logger tasks run more or less in sequence. In pipeline mode, data logger tasks run more or less in parallel. However, when the data logger program is compiled, the data logger analyzes the program instructions and automatically determines which mode to use.

How is the register file organized in AVR32?

The register file is organized as 16 32-bit registers and includes the Program Counter, the Link Register, and the Stack Pointer. In addition, one register is designed to hold return values from function calls and is used implicitly by some instructions.

When did the AVR microcontroller family come out?

The AVR family was launched by Atmel in 1996 and has had remarkable success in the 8-and 16-bit flash microcontroller market. AVR32 is complements the current AVR microcontrollers.

Why are 16 bit instructions used in AVR32?

In order to achieve high code density, the instruction format is flexible providing both compact instructions with 16 bits length and extended 32-bit instructions. While the instruction length is only 16 bits for most instructions, powerful 32-bit instructions are implemented to further increase performance.

What kind of microprocessor is the AVR32?

The AVR32 is a new innovative microprocessor architecture. It is a fully synchronous synthesis- able RTL design with industry standard interfaces, ensuring easy integration into SoC designs with legacy intellectual property (IP).
