JPCT Requirements

[enbe11_3]

HI,
   I was wondering if JPCT could run in a OLPC... ?

OLPC hardware:

CPU: AMD Geode LX-700 - x86-compatible processor with 64KB each L1 I and D cache; at least 128KB L2 cache; AMD Geode LX-700@0.8W;

CPU clock speed: 433 Mhz;

ISA compatibility: Support for both the MMX and 3DNow! x86 instruction-set extensions; Athlon instruction set (including MMX and 3DNow! Enhanced) with additional Geode-specific instructions;

Companion chips: PCI and memory interface integrated with CPU; North Bridge: PCI and Memory Interface integrated with Geode CPU; AMD CS5536 South Bridge (datasheet);

Graphics controller: Integrated with Geode CPU; unified memory architecture;

Embedded controller: ENE KB3700 or ENE KB3700B;

DRAM memory: 256 MiB dynamic RAM;

Data rate: Dual — DDR333 — 166 Mhz;

1024KB SPI-interface flash ROM;

Mass storage: 1024 MiB SLC NAND flash, high-speed flash controller;

Drives: No rotating media;

jPCT requires a Java-VM and, for hardware rendering, an OpenGL compatible graphics hardware. Otherwise, it's software rendering only. If the OLPC offers this, jPCT should run.

OLPC don't have a compatible graphics hardware, but my idea is to make 3d applications with
the jPCT 3d software rendering.

There's only one problem(i think). -The bare minimum for simpler applications is a 450Mhz cpu - (http://www.jpct.net/requirements.html) and OLPC cpu is an AMD Geode LX 700 - 433mhz  ...

is it possible to run a jPCT simpler application in a 433mhz cpu? 

thanks!

(sorry for my bad english)

Yes, you can run it on lower end hardware. The question is only how fast that will be. I've no idea what to expect from an AMD Geode processsor performance wise, but just give it a try...

i will  , thanks again
