What's ARM doing in the DSP market?

ARM has not only revolutionised the embedded processor market in a way Intel could not have imagined 20 years ago. It is also changing the very different world of digital signal processing (DSP). Microcontrollers are not designed for real-time processing and so the DSP function has to be added…

Comment: Can ARM dominate mobile GPUs too?

Samsung’s decision to use more ARM processor cores in its smartphones and tablets is not surprising. But these are not Cortex-A series processors they are Mali graphics processing units (GPUs). ARM rival Imagination has the GPU of choice for the mobile market. Apple, Samsung, Motorola, Nokia all use…

Samsung extends ARM licence for all Mali GPUs

Samsung Electronics has extended its licensing deal for ARM Mali graphics processors. What is called a “subscription licence” covers Mali graphics processing units (GPUs) including the Mali-T820/830/860, the recently announced T880 and all future Mali GPUs. Samsung Electronics already licences the graphics processor IP for SoCs. “The…
