Abstract

"SISTEMA DE ADMINISTRAçãO DE MEMóRIA TEMPORáRIA PARA CONTROLAR EM UM SISTEMA DE COMUNICAçãO DE DADOS UM ATRASO DE UMA UNIDADE DE DADOS, RECEPTOR DE áUDIO DIGITAL, FONES DE CABEçA, GABINETE DE ALTO FALANTE DE SOM CIRCUNDANTE INDEPENDENTE, MéTODO DE CONTROLAR EM UM SISTEMA DE COMUNICAçãO DE DADOS UM ATRASO DE UMA UNIDADE DE DADOS, E, PRODUTO DE PROGRAMA DE COMPUTAçãO". O sistema de administração de memória temporária (100) é arranjado para controlar em um sistema de comunicação de dados um atraso de ponta a ponta (<30>) de uma unidade de dados (150) de entrada para saída. Blocos (104, 106) de unidades de dados (150, 152) são escritos em uma memória temporária (102) com uma taxa de escrita de bloco (Rw), e unidades de dados (154, 156) são lidas desta memória temporária (102) com uma taxa de leitura (Rr). O atraso de ponta a ponta (<30>) é controlado adaptando a taxa de leitura (Rr) da memória temporária (102), e conseqüentemente o enchimento de memória temporária (F) na base de medições de atrasos no sistema de administração de memória temporária (100). Para o cálculo da taxa de leitura (Rr), pelo menos uma medição de tempo de entrada (mTa) de um instante de tempo de entrada (Ta) de entrada da unidade de dados (150) no sistema de administração de memória temporária (100) é requerida.
