{ "item_title" : "State Machines in VHDL Trigonometric Functions Vol. 4", "item_author" : [" Daryl Ray Hawkins "], "item_description" : "A digital designer's book devoted entirely to trigonometry, first of its kind. Relevant theory and graphical illustrations are also provided. Table-based solutions include all core functions and their reciprocals, as well as inverse functions and their reciprocals. Each with an implementation in both degrees and radians, twenty-four in all. The list includes: sine, cosine, and tangent, and their reciprocals: cosecant, secant, and cotangent. Inverse functions: arcsine, arccosine, and arctangent, as well as their reciprocals: arccosecant, arcsecant, and arccotangent. Real-Time solutions provide high to very high precision utilizing Taylor polynomials for core functions and Borchardt-Gauss using iterated means (variant of Arithmetic-Geometric Mean) for their inverse functions, radians only. Included are: sine, cosine, tangent, and their inverse arcsine, arccosine, and arctangent. All designs are fully coded utilizing state machines in VHDL. Each have associated diagrams, tables, and operational parameters. Implementations are fixed-point and have scalable operands based on constants.", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/1/50/878/069/1508780692_b.jpg", "price_data" : { "retail_price" : "24.99", "online_price" : "24.99", "our_price" : "24.99", "club_price" : "24.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
