This paper presents a methodology for designing bipar-tite tables for accurate function approximation. Bipartite tables use two parallel table lookups to obtain a carry-save (borrow-save) function approximation. A carry propagate adder can then convert this approximation to a two's complement number or the approximation can be directly Booth encoded. Our(More)
In this paper, we present a full-static carry-skip adder designed to achieve low power dissipation and high-performance operation. To reduce the adder's delay and power consumption, the adder is divided into variable-sized blocks that balance the inputs to the carry chain. The optimum block sizes for minimizing the critical path delay with complementary(More)
This paper presents a high-speed method for computing elementary functions using parallel table lookups and multi-operand addition. Increasing the number of tables and inputs to the multi-operand adder significantly reduces the amount of memory required. Symmetry and leading zeros in the table coefficients are used to reduce the amount of memory even(More)
Purpose. Chondrosarcoma (CS) most commonly involves the pelvis. The factors that influence local and systemic control of pelvic CS and the functional outcome should be evaluated.Patients. Fifty-one patients (37 males and 14 females; mean age, 39.4 years) with pelvic CS were included in this retrospective study.Methods. The tumor stage, surgical treatment,(More)
