A particular function may include one or more input intrusion intervals where generic fixed-point approximation methods are not sufficiently precise. Output values for these intrusion intervals may be pre-computed during function generation time using a mathematical library running on a computer-aided design tool and stored in a lookup table. During normal operation of the integrated circuit, a multiplexing network may be used to select among values generated by generic approximation methods and values obtained from one or more lookup tables depending on the current input to the function."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods for implementing arithmetic functions with user-defined input and output formats","description":"Methods for implementing fixed-point functions with user-defined input/output ranges and formats on a programmable integrated circuit are provided.
