The optimization

Posted on by lechuck park

This diagram illustrates the fundamental purpose and stages of optimization.

Basic Purpose of Optimization:

Optimization

  • Core Principle: Perform only necessary actions
  • Code Level: Remove unnecessary elements

Two Goals of Optimization:

1. More Speed

  • O(n): Algorithm (Logic) improvement
  • Techniques: Caching/Parallelization/Recursion optimization

2. Less Resource

  • Memory: Reduce memory usage
  • Management: Dynamic & Static memory optimization

Optimization Implementation Stages:

Stage 1: SW Level (Software Level)

  • Code-level optimization

Stage 2: HW Implementation (Hardware Implementation)

  • Offload heavy workloads to hardware
  • Applied when software optimization is insufficient

Optimization Process:

Input → Processing → Output → Verification

  1. Deterministic INPUT Data: Structured input (DB Schema)
  2. Rule-based: Apply rule-based optimization
  3. Deterministic OUTPUT: Predictable results
  4. Verification: Validate speed, resource usage through benchmarking and profiling

Summary:

Optimization aims to increase speed and reduce resources by removing unnecessary operations. It follows a staged approach starting from software-level improvements and extending to hardware implementation when needed. The process ensures predictable, verifiable results through deterministic inputs/outputs and rule-based methods.
