O processo de codificação/decodificação do JPEG2000 requer muito mais poder de computação do que o do JPEG convencional, principalmente devido à complexidade da codificação/decodificação da entropia. Assim, normalmente, vários módulos de hardware de codec de entropia são implementados em paralelo para processar a codificação/decodificação de entropia. Este módulo, no entanto, requer muitas memórias de tamanho pequeno para armazenar dados intermediários, e quando múltiplos módulos são implementados em um chip, o emprego de um grande número de SRAMs aumenta a dificuldade de layout de todo o chip. Neste artigo, é proposta uma estrutura de organização de memória eficiente para o módulo de codificação/decodificação de entropia, na qual não apenas as organizações de memória existentes, mas também nossos novos métodos de organização de memória propostos, são tentados para expandir o espaço de design a ser explorado. Como resultado, a organização eficiente da memória para uma tecnologia de processo alvo pode ser explorada.

Abstract: The encoding/decoding process of JPEG2000 requires much more computation power than that of conventional JPEG mainly due to the complexity of the entropy encoding/decoding. Thus usually multiple entropy codec hardware modules are implemented in parallel to process the entropy encoding/decoding. This module, however, requests many small-size memories to store intermediate data, and when multiple modules are implemented on a chip, employment of the large number of SRAMs increases difficulty of whole chip layout. In this paper, an efficient memory organization framework for the entropy encoding/decoding module is proposed, in which not only existing memory organizations but also our proposed novel memory organization methods are attempted to expand the design space to be explored. As a result, the efficient memory organization for a target process technology can be explored.
