Pyra: Full Prototypes Soon!

keymat-CAD-top

As we are soon jumping in the 4th quarter of 2015, things are getting progressively in place for the Dragonbox Pyra, with full prototypes to be assembled within November. The remaining elements are now being produced: the keymat, following its layout finalization, is now in production and samples of the real thing will be available by Mid-October. Once received we will see how it works hands-on, and if keys are lighted up as expected via the backlights.

What the Pyra Should Look Like : Renders

rendertop

As Evil Dragon (the leader of the Pyra handheld project) mentioned before, the case is more or less finished, and last week there was a final poll as well to decide the layout of the keyboard. While the layout will be tweaked further, those renders are pretty close to what the Pyra is supposed to look like later this year. [ Note, this article was updated again on July 30th with new content. ]

So, What’s the Open Pandora Community Made Of ?

topsurvey

Ola. Hold your horses, Sir. I know this survey was conducted in October and I see your gun pointed at me, asking me why it took so long to deliver the results. Well, analysis is one of the stuff that requires time and skills. And the more data you get, the more time it takes to go through to make good value of it, and look at segmentation and stuff like that (and you are never really over with it). Hopefully by reading this article you will understand why it took a while.

Speeding Up PS1 Emulation with OMAP’s DSP

topdsp

For a long time, most developers could not make good use of DSP comprised in the OMAP architecture of the Pandora SoC. Sure, there was TI’s dispbridge driver in the Pandora firmware for a long time, and a few developers like MH-T or Hdonk tried to make use of it – but the key issue was always linked with the latency to call the DSP or high CPU usage. Then BSP came with his deep knowledge of the architecture, and was able to package a kernel driver, a DSP component and an ARM library to make better use of it. Unfortunately, while the DSP can certainly help to relieve your CPU of certain tasks , it requires to re-factor your code and separate it into parallel processes to be used in concurrence with the main program thread. With the exception of a few demos by BSP, MH-T and Hdonk, no one had yet fully completed that kind of work. Notaz’s latest PCSXReARMed build now makes full use of that architecture.

I Like it in Aluminium, Baby

In a surprising turn of events, it turns out that while the Pandora is reaching the end of its life (as the number of units to be produced is running out), there are still interesting hardware/design related projects out there. Following the recent release of source files for the case design, someone has shown interest in developing an aluminium case for the Pandora. Excellent!
