SEGGER's Ozone Debugger Now Supports Custom Instructions

December 26, 2019 Perry Cohen

SEGGER announced the release of Ozone V3.10, a major update to its full-featured graphical debugger and performance analyzer. The new release includes support for custom instructions, allowing disassembly of application specific instructions added to the CPU core to tailor it for the particular application. Custom instructions are defined in plug-in scripts, which can be edited by the user of Ozone or the CPU core designer. The software already comes with a plug-in script for the popular RISC-V PULP extension.

Custom instructions are used to make embedded systems more efficient. Tailoring instructions to a specific application increase speed and reduces power consumption. The use of customized instructions, now available for RISC-V and ARM, is becoming more widespread.

Ozone V3.10 comes with other new features and enhancements including a new unified timeline window. The unified timeline window shows all time-related values in a single window, so that instruction trace, power consumption, and data values can be viewed at a glance.

Ozone works cross-platform for Windows, macOS, and Linux. Like most SEGGER software, it can be downloaded and installed without a registration process. Ozone is available for free with a J-Link PLUS, PRO, ULTRA+, or with a J-Trace.
