Information processing apparatus for entertainment system utilizing DMA-controlled high-speed transfer and processing of routine data

An information processing apparatus, comprising:

• a main processor unit including at least computational processing means and cache storage means for storing non-routine data;
• main storage means;
• a floating decimal point vector processing unit including at least vector processing means and direct-memory-accessible internal high-speed storage means for storing routine data, said routine data including large volume data used for digital signal processing and accessed in a streaming manner;
• means for classifying data into said routine data for routine processing and said non-routine data for processing via said cache storage means;
• a direct memory accessing control unit for direct memory access transfer control of said routine data between said internal high-speed storage means and said main storage means, wherein said direct memory accessing control unit operates only on said routine data;
• and
• a main bus, wherein said main processor unit, said main storage means and said direct memory accessing control unit are interconnected over said main bus.
