What is the primary purpose of a Tensor Processing Unit (TPU)?

To improve cache memory hierarchy

To enhance parallel processing capabilities

To speed up machine learning applications (correct)

To increase I/O transfer rate

What is a limitation of multiprocessors in computer systems?

Improvements in one aspect do not result in proportional improvement in performance (correct)

They require significant changes to software

They are only used for I/O transfer rate optimization

They cannot be used for parallel processing

What is a benefit of using multiple core processors in a computer system?

Reduced power consumption

Enhanced security features

Improved performance for single-threaded applications

Increased parallel processing capabilities (correct)

Why do advancements in technology not always result in equal improvements in computer system performance?
