Technical whitepapers on architecture and high-level capabilities of Alif microcontrollers and fusion processors
Fusion Processors System Architecture Introduction
This white paper describes the key elements of the Ensemble family devices including the software execution environments, memories, peripherals, application development workflows, as well as the boot process, security features, and power management options.
(v2.0) This white paper details the innovative power management architecture of Ensemble family devices that allows dynamic control of power to various regions of the device to achieve industry-leading battery life.
This white paper describes the SRAM banks in the Ensemble family devices and their differences so that they can be best utilized by the application software.
This white paper looks at the comparative performance of current toolchains for the Cortex-M55 CPU as used in Alif MCUs and Fusion Processors and digs into the background and the underlying new optimization issues.
(v1.0) This white paper describes the steps of how a machine learning model that was trained and converted to a TFLite (quantized) format, needs to be further processed so it can take advantage of the Ethos U55 NPU accelerators in Alif Ensemble devices.
The Conductor Tool makes getting started with these Alif processors and microcontrollers easy, even for complicated configurations. New designers have a leg up thanks to this tool, and returning users know their configuration setup will be fast and pain free.
Deploying NVIDIA TAO Models on Alif Hardware With Edge Impulse
Edge Impulse has created an IDE for building TAO models and mapping them to supported hardware including a number of GPUs, NPUs, and MCUs. Alif Semiconductor’s Ensemble® family of microcontrollers, offers a dedicated NPU (Arm® Ethos™-U55) to run complex AI/ML workloads and has partnered with Edge Impulse to allow engineers to map and accelerate their modified ML algorithm on Alif’s hardware.
Diving Into Alif Semiconductor’s Secure System Architecture and Secure Boot Process
This whitepaper discusses Alif Semiconductor’s “Secure Enclave”: an independent, isolated security subsystem as well as Alif’s secure 4-stage lifecycle management. Furthermore, we will discuss how this builds on conventional measures to ensure endpoint device security against common threats (e.g., malware, data theft, network breach, IP theft, cloning, rollbacks) such as TrustZone, Root of Trust, etc., with unique security services and a flexible configuration matrix.
