Abstract

"EQUIPAMENTOS E MéTODO PARA CODIFICAR E COMPUTAR UMA TRANSFORMADA DE COSSENO DISCRETA USANDO UM PROCESSADOR BORBOLETA". Um equipamento para determinar uma transformada de um bloco de dados codificados, o bloco de dados codificados compreendendo uma pluralidade de elementos de dados. Um registrador de entrada é configurado para receber uma quantidade predeterminada de elementos de dados. Pelo menos um processador borboleta é acoplado ao registrador de entrada e é configurado para executar pelo menos uma operação matemática em pares selecionados de elementos de dados para produzir uma saída de elementos de dados processados. Pelo menos um registrador intermediário é acoplado ao processador borboleta e configurado para armazenar temporariamente os dados processados. Um loop de feedback é acoplado ao registrador intermediário e ao processador borboleta e, caso habilitado, é configurado para transferir uma primeira porção de elementos de dados processados ao processador borboleta apropriado para executar operações matemáticas adicionais e, caso desabilitado, é configurado para transferir uma segunda porção de elementos de dados processados a pelo menos um registrador de armazenamento.
