The FIFO buffer receives a variable size data from the BIU and stores the variable size data at a write address. The FIFO write logic module generates a write pointer by encoding the write address using a Johnson code. The FIFO read logic module receives a synchronized write pointer at the asynchronous clock domain and generates a read address signal when the synchronized write pointer is a valid Johnson code format. The FIFO buffer transfers the variable size data to a processor based on the read address signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Asynchronous FIFO buffer with Johnson code write pointer","description":"An asynchronous data transfer system includes a bus interface unit (BIU), a FIFO write logic module, a write pointer synchronizer, a write pointer validator, a FIFO read logic module, and an asynchron","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9710415","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.
