The methods and systems are designed to achieve, among other things, lower cost, longer battery life, and faster user response. Whereas existing approaches for memory management are based on pixel or frame buffer compression, the methods and systems provided focus on the CPU's program (e.g., generic data structure). Focusing on hardware-accelerated memory compression to offload CPU translates higher power efficiency (e.g., ASIC is approximately 100× lower power than CPU) and higher performance (e.g., ASIC is approximately 10× faster than CPU), and also allows for hardware-assisted memory management to offload OS/kernel, which significantly increases response time."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hardware-assisted memory compression management using page filter and system MMU","description":"Provided are methods and systems for managing memory using a hardware-based page filter designed to distinguish between active and inactive pages (“hot” and “cold” pages, respectively) so that inactiv","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9740631","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
