Sony PRS-T1 and Kindle Touch CPU
Hi,
Is this the right way? I was told to post a new thread in the dev corner? Do you guys know what cpu/processor is Sony PRS-T1 and Kindle Touch (SO) using? Both seems to be Freescale / ARM family based. (Kindle Keyboard is documented on the matrix as i.MX35.) But because both are so new, I couldn't find anything on the web. Just thought you guys might know. Thank you so much in advance. |

I have not seen any info on the SoCs. Note that the Kobo and B&N Touch devices are relatively new and both use a 800 MHz clock, but the Kobo (and the iRiver HD) have a Freescale i.MX508 vs a TI OMAP3621 on the B&N. If I had to guess I would vote for the Freescale on the Kindle and (perhaps) the TI on the Sony.
EDIT: the Kindle 4 is using an i.MX50 family cpu, see Analyzing Kindle 4.0. Probably the same on the Kindle Touch. Last edited by wallcraft; 09-30-2011 at 06:56 PM. |

The Kindle 4 is built for the iMX50 (800MHz ARM Cortex A8) platform. The Kindle 3 is iMX35 (532MHz ARM). The Kindle 2/DX is iMX3 (400MHz ARM). I assume those are the actual in-device running clock rates. -Pie |

Does anybody know what PRS-T1 is packing? It's curious, K-Touch was out 2 days ago, and we already know, but not PRS-T1 when it is announced back in Aug. 31st.. |

I found multiple articles that say the T-1 uses a 1GHz Intel processor, but no specifics on exactly which specific "1GHz Intel processor."

Correct me if I am wrong. Also, if this was the case, it is the FIRST cpu/processor on the entire ebook reader matrix that has an Intel inside. So, I don't think this is true. (Given the nature of ebook readers, I am not surprised no body asked or tear down the device...) CORRECTION: Fujitsu FLEPia has a Intel XScale RISC CPU, but I don't know the clock speed on that one. And It is for the color ebook display as well, so it is possible, still think it is unlikely. Last edited by azxswq; 10-01-2011 at 01:20 AM. |

You are probably correct.

Am I missing something obvious here? Are you showing me the result of some cpu/kernel dump that I don't have access to? So you are basically saying that Kindle 4 and PRS-T1 are roughly the same, right? 800MhZ, Dual core, Cortex... Thanks anyways! Last edited by azxswq; 10-04-2011 at 12:37 AM. |

The T1 definitely has a 800MHz Freescale MX50 ARMv7
cat /proc/cpuinfo yields Code:
Processor : ARMv7 Processor rev 5 (v7l) BogoMIPS : 799.53 Features : swp half thumb fastmult vfp edsp neon vfpv3 CPU implementer : 0x41 CPU architecture: 7 CPU variant : 0x2 CPU part : 0xc08 CPU revision : 5 Hardware : Freescale MX50 ARM2 Board Revision : 50011 Serial : 0000000000000000 Edit: RAM seems to be 256MB Android version 2.2.1 Last edited by uboot; 11-13-2011 at 05:45 PM. |
