What is the primary architectural objective of integrating a special-purpose coprocessor (e.g., DSP, GPU, NPU, or cryptographic accelerator) alongside a general-purpose CPU?
Multiple Choice Options
- A
To execute general-purpose system operating system kernels
- B✓ Correct Option
To offload and accelerate specific, computationally intensive domain algorithms with high parallelism and energy efficiency
- C
To replace system memory buses with analog delay lines
- D
To eliminate software compilation completely
Detailed Technical Solution & Explanation
Special-purpose processors (Domain-Specific Architectures such as GPUs for SIMD vector rendering, DSPs for FFT and MAC signal processing, and NPUs for tensor matrix multiplication) feature custom silicon datapaths optimized for specific computational patterns. By offloading these repetitive, highly parallel mathematical kernels from the host CPU, they achieve orders-of-magnitude higher throughput and energy efficiency.
