Embodiment Construction

[0041] Referring now to FIG. 1, there is shown an exemplary configuration of an image display device according to the present invention.

[0042] In FIG. 1 , an image display device 1 displays moving images and still images encoded by JPEG (Joint Photographic Experts Group, Joint Photographic Experts Group) on the following display devices. The image display device 1 processes image data, such as JPEG image data, supplied through an input terminal or stored in a semiconductor memory 2 composed of an electronically rewritable nonvolatile memory such as flash memory.

[0043] A first CPU (Central Processing Unit, Central Processing Unit) 11 of the image display device 1 performs image processing such as decoding on image data acquired from the semiconductor memory 2 through the memory card interface 22, and supplies the processed image data to the graphics Controller 23.

[0044] Also, the first CPU 11 controls the component blocks interconnected via the bus. In addition, the ...

Abstract

The present information relates to an information processing apparatus and method, a recording medium, and a program which are capable of easily and continuously writing programs to a plurality of storage blocks which are controlled by different CPUs. A first CPU 11 of an image display apparatus 1 writes a subject file from a semiconductor memory 2 to a specified device, a first flash ROM 12 or a first EEPROM 14 . Alternatively, the first CPU 11 controls a second CPU 31 to write a subject file to a specified device, a second flash memory ROM 32 or a second EEPROM 34 . While executing normal processing, the first CPU 11 confirms whether a subject file to be installed is ready or not. If the subject file is found to be ready, the first CPU 11 starts installing the subject file. The present invention is applicable to personal computers.

Description

technical field [0001] The present invention generally relates to an information processing apparatus and method, a recording medium, and a program. More particularly, the present invention relates to, in an information processing apparatus having two or more different CPUs and storage units, easy and continuous writing of programs into two or more storage units under the control of different CPUs An information processing apparatus and method, a recording medium, and a program of capabilities. Background technique [0002] For example, it is well known that a program and data are recorded in a ROM (Read Only Memory) before shipment to control a video display device. As another option, programs and data can be recorded in RAM (Random Access Memory) or hard disk drive for later updating. [0003] For example, if there is a problem with a program or data written into any of these storage devices before shipment or additional new functions are added, the new program or data i...
