What is a Nintendo 3DS?




A

portable game console

produced by

Nintendo
. It is an

auto stereoscopic

device
capable of projecting

stereoscopic 3D

effects without the use of

3D glasses

or additional accessories


How does it work?



The Nintendo

3DS system has two separate screens. The top screen is a 3.53

in
(90

mm) 15:9

(5:3)

auto stereoscopic

(3D)

LCD

screen with a resolution of 800×240 pixels (400×240
pixels per eye,

WQVGA
) that is able to produce a three
-
dimensional effect without 3D glasses

using
a

parallax barrier
. There is a

3D Depth Slider

next to the 3D screen which allows the user to adjust the
intensity of the 3D effect. The bottom screen is a 3.02

in (77

mm) 4:3 2D

resistive touch screen

with a
resolution of 320×240 pixels (
QVGA
). The

3DS weighs approximately 230 grams (8.1

oz) and, when
closed, is 134

mm (5.3

in) wide, 74

mm (2.9

in) broad, and 21

mm (0.83

in) thick.




The system features three camera sensors:

two cameras

on the outside of the device,
capable of taking 3D photos and
capturing 3D video; and one camera in the front side/inside of the device
positioned above the top screen which faces the player, and is capable of taking 2D photos and capturing
2D video. These photos can be edited with various effects such as props, 3D d
epth and colors. All
camera sensors have a maximum resolution of 640×480 pixels (0.3

megapixels
,

VGA
) and can only
achieve

digital zoom
. There is also a
microphone

in the bottom of the system.



The Nintendo 3DS system utilizes a custom components co
-
devel
oped by Nintendo in
conjunction with other manufacturers, all combined into a unified

SOC
. The

main processor

(CPU) is
designed by

ARM
, and consists of a

ARM11 MPCore
-
based dual
-
core processor manufactured at

45

nm
.
The

graphics processor

(GPU) is designed

by

Digital Media Professionals (DMP)
, and consists of
a

PICA200

processor.

The system contains 128

MB

of system memory consisting of two 64

MB
(512

Mb)

FCRAM

chips developed by
Fujitsu
, with a maximum bandwidth of 3.2

GB/s, in which 32

MB
are reserved for

the operating system and unavailable to apps. The system also contains 6

MB of

VRAM
.
The console also includes two secondary custom processors that handle undisclosed tasks. These tasks
are handled seamlessly in the background during game play or while th
e system is in

sleep mode
. The
console also contains a dedicated hardware audio

DSP

module capable of outputting

mono
,

stereo

or
pseudo
-
surround sound through its two speakers and

headphone jack
.



The system includes 1

GB of internal

flash memory

manufact
ured by

Toshiba
, but it's
mostly used by the

operating system
. The system's memory can be expanded via an

SD

memory card
slot, which supports up to 128

GB

SDXC
, up to 32

GB

SDHC

and up to 2

GB

SD

memory cards. All
Nintendo 3DS systems include a 2

GB SD car
d while Nintendo 3DS XL and Nintendo 2DS systems
include a 4

GB SDHC card. The system uses 2.4

GHz

802.11 b/g

wireless network

connectivity with
enhanced security

WPA2
.

There is also an infrared port on the back of the console, which allows the
system to c
onnect with certain peripherals such as the

Circle Pad Pro
.
