			<content:encoded><![CDATA[<p><a href='http://www.imore.com/images/stories/2008/11/ipod_touch_faster_iphone_3g.jpg'><img src="http://www.imore.com/images/stories/2008/11/ipod_touch_faster_iphone_3g.jpg" alt="" title="ipod_touch_faster_iphone_3g" width="497" height="217" class="aligncenter size-full wp-image-5668" /></a></p>

<p>Imagination makes the <a href="http://www.imore.com/tag/powervr/">PowerVR graphics core</a> chip (GPU) that powers the current generations of iPhone and iPod touch handsets. Apple likes them enough to have become a huge licensor and even investor in the company. Well, it&#8217;s looking like that investment may pay off for iPhone users in the <em>next</em> generation iPhone and iPod touch (which TiPb is still <a href="http://www.imore.com/2008/10/10/tipb-predicts-iphone-hd-in-2009/">predicting</a> will hit in July and September respectively). </p>

<p>Even bigger news? It looks like these new multi-core chips will be transparent from the developer&#8217;s point of view. That means Apple has far less risk in &#8220;fracturing the platform&#8221; by adding more GPU firepower to the next gen iPhone. Also, they look to be supporting OpenCL, Apple&#8217;s open source implementation that allows GPUs to be treated like CPUs and boost general purpose computing when they&#8217;re not throwing polygons and pixels around our favorite games or movies.</p>

<p>Says the <a href="http://www.theregister.co.uk/2009/03/18/sgx543mp/">Register</a> (via <a href="http://www.macrumors.com/2009/03/18/multi-core-gpus-announced-from-iphone-chip-maker/">MacRumors</a>):</p>

<blockquote>
  <p>Without any intervention by the application &#8211; and, more importantly, without any intervention by the application&#8217;s developer &#8211; the driver will pass data to an &#8220;MP code scheduler,&#8221; which will in turn pass that data to one pipeline scheduler per core, which will then pass it to one thread scheduler per multi-threaded processing engine, which will then manage the threads through the engines as they process the graphics data.</p>
  
  <p>In other words, the SGX543 can have any number of cores from two to sixteen with no change in the driver software or the application. All that complex data/pipeline/thread management is done in hardware. No muss, no fuss.</p>
</blockquote>

<p>But a whole lot of &#8220;we want it now!&#8221;&#8230;</p>

			<content:encoded><![CDATA[<p><img src="http://www.imore.com/images/stories/2008/11/ipod_touch_faster_iphone_3g.jpg" alt="" title="ipod_touch_faster_iphone_3g" width="497" height="217" class="aligncenter size-full wp-image-5668" /></p>

<p>The iPhone can play 3D games and pump out high quality video like almost no other handset on the market, but when you&#8217;re not gaming or watching video, when you&#8217;re just using apps or doing old-school computing, all that power goes to waste, right?</p>

<p>Well, maybe not for much longer.</p>

<p><a href="http://www.imore.com/tag/powervr/">PowerVR</a> from Imagination is the graphics and video processor core inside the iPhone (and other mobile devices), and we mentioned earlier in the week that it&#8217;s now confirmed <a href="http://www.imore.com/2008/12/18/official-apple-secret-licensee-powervr/">Apple is a mega-licensee</a> of the technology moving forward.</p>

<p>Now <a href="http://www.appleinsider.com/articles/08/12/20/future_iphones_to_wield_opencl_acceleration.html">Apple Insider</a> reports that Imagination is looking for OpenCL engineers.</p>

<p>While OpenGL is the open source competitor to Microsoft&#8217;s proprietary DirectX graphics technology (the stuff that drives all those 3D games), <a href="http://en.wikipedia.org/wiki/OpenCL">OpenCL</a> (Wikipedia link) has recently been open sourced by Apple for leveraging that power for mainstream computing tasks. And Imagination integrating OpenCL means Apple&#8217;s desktop OS X 10.6 Snow Leopard might not be their only OS to benefit&#8230;</p>

<p>Hello GPU accelerated general iPhone processing! Hopefully this means regular old applications, from data bases to web code processing will soon be snappier, and more powerful.</p>

<p>Um&#8230; now please?</p>
