What is the primary goal of energy-efficient computer architectures?
Reduce energy consumption while maintaining performance
Increase clock speed regardless of energy use
Focus solely on reducing device weight
Enhance graphics processing capabilities
The primary objective of energy-efficient architectures is to deliver high performance while reducing power consumption. This balance is key for sustainable and high-performance computing designs.
What does processing in memory (PIM) aim to achieve in computer architecture?
Increasing the physical size of memory arrays
Encrypting data stored in memory
Shifting data processing tasks closer to the memory to reduce latency
Offloading processing tasks to the cloud
Processing in Memory (PIM) reduces the need to move data between memory and processors, thereby reducing latency and energy costs. This integration enhances overall system efficiency.
In cloud computing architectures, what is a key benefit of virtualization?
Efficient resource utilization and scalability
Reduction in physical server numbers by half regardless of usage
Increased disk storage capacity
Unnecessary duplication of data
Virtualization allows for the efficient allocation of computing resources by creating virtual instances on a single hardware platform. This enhances scalability and optimizes resource utilization in cloud computing.
Which feature best describes a heterogeneous computing platform?
Focusing solely on scalar processing
Elimination of modular design
Integration of different types of processors (e.g., CPU, GPU) to optimize workload
Use of identical processors for all tasks
Heterogeneous computing platforms leverage different types of processors to best match various workloads. This design provides improved performance and energy efficiency by assigning tasks to the most suitable processing unit.
What is one benefit of using 3-D architectures in chip design?
Simplified chip manufacturing by using a single layer
Improved performance and reduced signal delay by stacking multiple layers
Lower cost by eliminating advanced cooling techniques
Increased chip thickness without performance gain
3-D architectures enable circuits to be stacked vertically, which shortens interconnect distances and reduces signal delay. This results in enhanced performance and efficiency in chip design.
How does approximate computing contribute to energy efficiency in certain applications?
By eliminating error-checking mechanisms entirely
By increasing the number of computing cycles
By focusing solely on precision over energy use
By allowing controlled imprecision in computations to reduce energy use
Approximate computing takes advantage of applications that can tolerate slight inaccuracies, thereby reducing energy consumption. This trade-off between precision and energy leads to more efficient processing in suitable scenarios.
Which of the following describes a primary challenge in secure computer architecture design?
Completely eliminating vulnerabilities through hardware alone
Removing all software layers to simplify architecture
Prioritizing speed over encryption
Balancing performance with robust security measures
Secure architecture design must reconcile the need for high performance with the implementation of strong security measures. This balancing act is a core challenge, as added security can introduce performance overhead if not carefully managed.
What is cross-stack design in computer architecture?
A stacking technique for physical memory modules
A design methodology only relevant for mobile computing
An approach that optimizes system performance by coordinating across hardware and software layers
A method focused exclusively on hardware improvements
Cross-stack design involves the coordinated optimization of both hardware and software layers. This integrated approach enables overall system improvements in performance and efficiency.
Which architectural innovation is particularly beneficial for machine learning workloads?
Reducing parallelism in processing tasks
Generic CPUs without specialized circuits
Machine learning accelerators that provide higher throughput for specific operations
Relying solely on traditional sequential processors
Machine learning accelerators are designed to handle the intensive computations often required in machine learning tasks. By providing increased throughput for specific operations, they make processing more efficient in these applications.
In what way do mobile computing architectures differ from traditional desktop systems?
They only implement one processing core
They prioritize energy efficiency and portability over raw computational power
They always feature higher clock speeds
They have no connectivity options
Mobile computing architectures are engineered to maximize energy efficiency and portability. These designs differ from desktop systems by balancing performance with battery life and size constraints.
Which design element is crucial to implementing hardware and software resiliency?
Using one single processor without backup
Dependence on outdated binary standards
Avoidance of any error-checking features
Redundancy and error correction mechanisms embedded in both hardware and software layers
Achieving resiliency in computing involves the ability to detect and correct errors both in hardware and software. Redundancy and robust error correction form the backbone of systems that can resist and recover from faults.
How can cloud computing architectures benefit from cross-layer (cross-stack) design approaches?
By focusing exclusively on physical server capabilities
By isolating hardware from software until the final processing stage
By ignoring virtualization mechanisms
By enabling better integration of software policies with underlying hardware resources, enhancing performance and scalability
Cross-layer design in cloud architectures bridges the gap between hardware resources and software policies, leading to more efficient resource allocation. This integrated approach enhances both performance and scalability.
What is a key consideration when designing 3-D architectures for thermal management?
Focusing solely on electrical performance
Stacking chips arbitrarily without thermal analysis
Ignoring thermal issues in favor of compact design
Efficient heat dissipation through improved cooling techniques and material selection
3-D architectures increase component density, which amplifies thermal challenges. Effective thermal management, including advanced cooling strategies and suitable materials, is essential to maintain performance and reliability.
In a heterogeneous computing system, what role does task scheduling play?
It assigns all tasks to the CPU to simplify architecture
It ignores differences between processors
It runs tasks randomly without system consideration
It allocates workloads to the most suitable processing unit to enhance performance and energy efficiency
Task scheduling in heterogeneous systems matches workloads with processors best suited to handle them. This intelligent mapping leads to improved performance and better energy utilization.
Which emerging technology is most associated with addressing complex security challenges in computer architectures?
Outdated antivirus software integrated in hardware
Single-layer security protocols
Manual encryption techniques performed by the user
Hardware-assisted security features like Trusted Execution Environments (TEEs)
Trusted Execution Environments (TEEs) provide a secure area within the processor, safeguarding sensitive operations from external interference. This hardware-assisted security is vital for addressing modern and complex security challenges.
