By using a contiguous block of memory that acts as a circular buffer, the memory address field of memory descriptors can be eliminated because the host system only need to inform the data movement engine of the length of each data transfer. The data movement engine can maintain pointers to keep track of the memory address in the host memory to read from and write to. After each data transfer, the relevant pointer can be incremented by a value corresponding to the length indicated in the memory descriptor for the transfer. As such, it is not necessary for the host system to provide the data movement engine with the memory address of each transfer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"DMA engine that generates an address-less memory descriptor that does not include a memory address for communicating with integrated circuit device","description":"To improve data throughput and data transfer rate, a contiguous block of host memory can be allocated for data transfers between the host system and an integrated circuit device such as a peripheral c","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11513986","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.
