HP Prime拆解与硬件配置
与卡西欧fx-CP400不同，HP Prime非常好拆。http://tiplanet.org/forum/gallery/image.php?mode=medium&album_id=194&image_id=2802
简述一下配置：
屏幕：3.5寸彩色TFT电容多点触屏，320*240 (QVGA) 114ppi 65000色(16bit) (对比卡西欧CP400，4.8寸320*528 128ppi)
CPU (U101): 三星ARM9 S3C2416XH-40 频率266/400MHz
内存(U200): Hynix H5MS2562NFR 32MB DDR400 SDRAM
闪存(U201): 三星 K9F2G08U0C-SCB0 - 256 MB
电池 : 3.7V锂离子1500 mAh (5.55Wh), 制造商：深圳市慧通天下股份有限公司

Complete article :)
Hi everyone,
Unlike the fx-CP400 which gave us a hard time (easy when you know the trick... ;) ), the HP Prime opens quite "easily" and reveals us its hardware:
http://tiplanet.org/forum/gallery/image.php?mode=medium&album_id=194&image_id=2802
We notice the references which were already at the back of our prototype: EA656MB for the motherboard and EA656KB for the keyboard and power board.
They include:
[*]Touch Color Display 3.5" diagonal with a resolution of 320x240px
[*]Processor (U101): Samsung S3C2416XH-40 - ARM9 clocked at 400 MHz maximum.
[*]RAM Memory (U200): Hynix H5MS2562NFR - 32 MB
[*]Flash Memory (U201): Samsung K9F2G08U0C-SCB0 - 256 MB
[*]Battery: Li-Ion 3.7V, 1500 mAh (5.55Wh)
In short, a fairly standard and simple architecture around three main distinct chips: RAM/ROM CPU.
Let’s now look at the details ;)
Processor :
[*] Architecture : ARM (ARM9 ; 32 bit)
[*] Core : ARM926EJ-S
[*] Manufacturer: Samsung
[*] Reference : S3C2416
[*] Specs : 16KB I-cache; 16KB D-cache/MMU
[*] Frequency : 2 Modes : 266 MHz and 400 MHz
[*] Note : Features 2D Acceleration
[*] Official "Product Brief" (PDF)
RAM Memory :
[*] Type : DDR SDRAM
[*] Manufacturer: Hynix
[*] Reference : H5MS2562NFR E3M
[*] Capacity : 32 MB (256Mb (x16 device) = 4M x 4Bank x 16 I/O)
[*] ManufacturerPage officielle
[*]Datasheet (Closest JFR MBdel)
Flash Memory :
[*] Type : Flash NAND
[*] Manufacturer: Samsung
[*] Reference : K9F2G08U0C SCB0
[*] Capacity : 256 MB (2 Gb)
[*]Datasheet
Screen :
[*] Type : TFT
[*] Manufacturer: ?
[*] Reference : ?
[*] Dimensions : 3.5" (8,9 cm)
[*] Resolution : 320×240 px
[*] Pixel density : 114 ppi
[*] Color : Yes , 16-bit;
[*] Other : Capacitive multi-touch layer
Battery :
[*] Type : Rechargeable Battery
[*] Technology: Lithium-Ion
[*] Manufacturer : WiseWod Tehnology Co.
[*] Reference : 484461AR
[*] IEC 61960 Number : 1ICP6/51/63
[*] Dimensions : 4.8 * 43.8 * 61 mm
[*] Nominal voltage: 3.7 V
[*] Max. capacity : 1500 mAh
[*] Energy: 5.55 Wh
[*] Impedance : <= 60 mΩ
In short, only documented and standard chips instead of proprietary ones or hidden in an ASIC, which is a nice change from the TI-Nspire or even more from the fx-CP400 :)
This calculator is positioning itself as a potential competitor to the TI-Nspire CX, as we wrote in our hands-on reviewand the hardware confirms this idea, despite a slight weakness in the RAM amount.
In fact, some people already think of a Prime emulator on the Nspire and a Nspire one on the Prime, given the similar architecture! (But first, the machine will have to be open to native development ;) )
You can also compare the technical specs of the CX and the Prime with our comparator :

See you later :)

软件的bug实在太多。。
试试正式版模拟器啊
查了一下处理器的资料，结合硬件配置，跑塞班应该不成问题

运行塞班有何意义，况且塞班又不是开放的平台，移植不大可能吧 imath 发表于 2013-8-9 19:28

我也觉得 320x240略弱
既然3.5吋不如直接用iPhone3Gs的480x320显示屏
好歹强一点 yzskyt 发表于 2013-8-9 23:42 static/image/common/back.gif

要是能刷nSpire的系统还不错 如果能找到JTAG测试点的话，在上面刷个WinCE不是问题，我玩过S3C2416。
顺便提下，S3C2416有两个版本，一个400MHz的，一个533MHz的，实测400MHz的超533MHz很简单很稳定。 nbzwt 发表于 2013-8-11 11:21 static/image/common/back.gif
