Symbian OS Makes its Debut as a Symmetric Multiprocessor System

Published by at

As well as a new promotional video targeted at developers that would make Terry Gilliam proud, the Symbian Foundation announced on their blog that the Symbian OS is now running under a symmetric multiprocessor system. Simply put, more than one CPU can connect to the main memory of a computer at the same time, allowing for any processor to work on any application thread, and have the tasks passed around the processors to keep everything running efficiently.

The contrast between the advert (below) and the technical details shows why the Symbian Foundation believe they are on to a winner. The Symbian OS has always been designed to run on smaller devices and make best use of the limited resources available on a mobile phone, and that means ever more complicated technology and systems, but at the same time ensuring the system retains a level of simplicity for both the end user and the first and third party developers.

There are some concerns in the comments that, using multiple processors, the battery usage could rise, and that is one area where technology does not make huge leaps every year in terms of capacity, but in fact the same load but shared over the processors will take up less power than on a single chip.

See below for some additional technical highlights and try and keep the drool to a minimum.

About the hardware :

  • Single chip base band and application processor engine
  • HSPA Modem Release7
  • ARM® Cortex™-A9 MPCore

Which can accommodate features and functionality such as :

  • HD 1080p camcorder and video
  • Up to 18 Million pixels camera
  • ~100 hours audio playback time
  • 10 hours HD video playback time
  • Simultaneously TV out over HDMI
  • Video and Imaging accelerator
  • HW accelerated 3D Graphics  supporting OpenGL ES2.0
  • 2xWVGA (960×854) displays
  • Touch UI on 2 displays

 

The full details and discussion are over on the Symbian Foundation blog.
