Abstract

MéTODO PARA CRIAR UMA REPRESENTAçãO DE UM RESULTADO DE CáLCULO LINEARMENTE DEPENDENTE DE UM QUADRADO DE UM VALOR. Na transição para a faixa logarítmica, não deve ser considerada a largura de bit inteira do resultado linearmente dependente do quadrado do valor. Ao invés disso, é possível escalonar o resultado de um valor com x bits, de modo que uma representação com menos que x bits do resultado seja suficiente para obter a representação logarítmica baseada neste. O efeito do fator de escala na representação logarítmica resultante pode ser compensado pela adição ou subtração de um valor de correção obtido pela função de logaritmo aplicada ao fator de escala ou da representação logarítmica escalonada sem qualquer perda de dinâmica. Desta maneira, são providos um método e um equipamento para criar uma representação de um resultado linearmente dependente de um quadrado de um valor, de modo que o cálculo é simples e/ou possível com pouca despesa com hardware.
