Enhanced function board for use in processing image data and image processing apparatus using the same
First Claim
1. An enhanced function board, which can be connected via a connector to an image processing apparatus that includes a CPU, a memory in which image data is stored, and a video signal processor for accessing said memory to read said image data and prepare a display image based on said image data under control of said CPU, the enhanced function board comprising:
- a pair of buses;
first and second digital signal processors respectively connected to said pair of buses;
a FIFO memory connected between said pair of buses for transferring data between said first and second digital signal processors; and
an interface circuit connected to said pair of buses, whereby said first and said second digital signal processors are connected via said interface circuit to said CPU and said video signal processor.

Abstract
A video game device is disclosed which is composed of a console apparatus in which a processor is installed to execute a game software program. The video game device also includes a memory device, such as a memory cartridge which is removably attached to the console apparatus and which stores the game program. An enhanced function board is attached to the main body of the video game device for improving and enhancing the functions of the video game. The enhanced function board includes a pair of buses, first and second digital processors connected to the buses, a FIFO memory connected between the buses, and an interface circuit connected to the pair of buses. The interface circuit operates to connect the first and second digital processors to the processor of the video game device.
