Arm Introduces New Image Signal Processors for IoT Devices


The new ISPs are incorporated with Arm’s Iridix technology and other market-leading algorithms for colour and noise management

Arm, a global semiconductor and software design company, launched a new generation of image signal processors (ISPs) for real-time higher image quality in Internet of Things (IoT) devices.

The new ISPs by Arm – Mali-C52 and Mali-C32 –  apply more than 25 processing steps to each pixel, out of that three crucial ones provide key differentiation with regards to quality of image output. These consist of high-dynamic range (HDR), colour management and noise reduction.

The new ISPs are incorporated with Arm’s Iridix technology and other market-leading algorithms for colour and noise management. Due to this, these latest ISPs efficiently offer high resolution and that too in real-time.

The latest ISPs are equipped with the dynamic range management and tone mapping technology of Arm. In addition, these are designed to overcome limitations of device in terms of HDR requirements and allow viewers to see enhanced shadows, without changing or touching the image highlights.

Highest possible image quality

Speaking on the development, Thomas Ensergueix, Senior Director – Embedded and Automotive Line of Business, Arm, said, “Achieving our vision of a world of a trillion connected devices will require a sharper digital eye for many of those devices to see and understand their environments in order to be reliable sources of information to both machines and humans. This all starts with enabling the highest possible image quality, and the new Mali ISPs that Arm is making available to the market today will deliver it.”

The latest ISPs are a complete solution as Arm provides the hardware IP combined with ISP software drivers, such as 3A libraries (auto-exposure, auto-focus and auto-white balance) and the tuning and calibration tools.

The Mali-C52 ISP is provided with a flexibility to be configured for two diverse optimisations including image quality and area. This enables the company’s partners to use the similar IP and software across a wide range of use cases and products.

The Mali-C32 is specifically designed for area in low-power, cost-sensitive embedded vision devices like hobby drones or entry-level access control.
