Abstract
A processing circuit capable of realizing an operation including a logarithm of 2 operation with a small scale circuit configuration, wherein a priority encoder and a shaft circuit normalize g data, a table outputs &mgr;=“log ({1, qm})−qm” corresponding to a mantissa qm, another shift circuit shifts data obtained by bit coupling a data maxe comprised by only an integer part and a &mgr; data toward the MSB by L, another shift circuit shifts data obtained by bit coupling an exponent qe and the mantissa qm toward the MSB by L, an adder circuit adds &dgr;2, &ggr;2, and {K, 3′b0, 10}, and a clamp circuit clamps the result of addition to a predetermined number of bits.
