Difficulty: Easy
Correct Answer: not always—performance and effort depend on the application
Explanation:
Introduction / Context:
Engineers often confront the hardware-versus-software trade-off when implementing a digital function (e.g., filtering, protocol handling, or control). While hardware may seem faster and software more flexible, absolutes rarely apply across all use cases.
Given Data / Assumptions:
Concept / Approach:
Hardware can provide parallelism and deterministic latency; software offers flexibility and simpler updates. However, whether hardware is faster or easier depends on the specific workload (compute intensity, I/O timing), available devices, and development environment. Thus, the only accurate general statement is that it depends on the application.
Step-by-Step Solution:
Verification / Alternative check:
Real-world designs often hybridize: offload hot paths to programmable logic, keep control flow in software, demonstrating that neither side “always” wins universally.
Why Other Options Are Wrong:
“Always faster,” “always slower,” and “always easier” are absolute claims contradicted by countless counterexamples. For instance, a fast CPU with SIMD can beat a small CPLD; conversely, a deeply pipelined FPGA can beat firmware for tight latency loops.
Common Pitfalls:
Assuming clock rate equals performance; ignoring memory bandwidth, I/O timing, and algorithm structure. Overlooking maintainability and field updates when choosing hardware-only solutions.
Final Answer:
not always—performance and effort depend on the application
