Alif Semiconductor Ensemble® & Balletto™ Development Services
Firmware, Edge AI, graphics and ultra-low-power engineering for Alif Semiconductor MCUs — from driver bring-up to production-ready products.
Sirin Software is an authorized Alif Semiconductor Design House. We provide embedded engineering for AI-ready, low-power products built on Alif Semiconductor Ensemble® and Balletto™ microcontrollers.
Our team has hands-on experience with the Ensemble E7, E8 and E1C and the Balletto B1 families. The work spans low-level drivers and hardware interfaces, middleware, Zephyr® RTOS integration and application examples.
We cover Edge AI on Arm® Ethos™-U55 and Ethos™-U85 NPUs, LVGL graphics with D/AVE 2D acceleration, Helium-accelerated image processing, TinyUSB, CMSIS-DAP and CMSIS-Pack tooling, Bluetooth® LE Auracast™, secure boot and sub-microampere power optimisation. Since 2014, Sirin Software has delivered 100+ hardware and firmware products for 50+ clients.
What We Do
Ensemble® MCU Development
Firmware for Ensemble E7, E8 and E1C devices: SDK integration, peripheral and driver development, RTOS integration and optimisation for compute-intensive and battery-powered applications. We build the platform layer - drivers, hardware interfaces, middleware - so application teams can work on product features instead of silicon details.
Edge AI on Ethos™-U55 & Ethos™-U85
Deployment of neural-network workloads on Alif's Arm Ethos™-U NPUs, with model preparation and compilation through the Vela compiler. We partition work between the Cortex® CPU and the NPU to meet performance, memory and power limits, and integrate models into application firmware rather than a separate AI subsystem. This includes audio ML pipelines: noise suppression, wake-word detection and closed-vocabulary processing with Helium-accelerated preprocessing.
Graphics: LVGL + D/AVE 2D
LVGL porting and integration on Alif platforms, connected to the D/AVE 2D hardware accelerator. Rendering operations are offloaded from the CPU to 2D hardware, giving responsive user interfaces while keeping CPU time for application, connectivity and control tasks.
Embedded Image Processing
A custom image-processing library for embedded vision pipelines: scaling, rotation, cropping, region of interest, colour correction (exposure, white balance, contrast, saturation) and raw image debayering. Each operation runs on the best-suited hardware - Arm Helium vector processing or D/AVE 2D - reducing load on the main CPU.
USB, Zephyr® & Developer Tooling
TinyUSB porting to Alif MCUs in device and host modes, integrated with Zephyr® RTOS, with example applications. We also work on the tooling around the silicon: CMSIS-DAP for standard Arm debug and programming workflows, and CMSIS-Pack preparation so Alif components work consistently across development environments.
Security, Bluetooth® LE & Ultra-Low Power
Secure Enclave Subsystem (SESS) provisioning, secure boot and Arm TrustZone® separation of trusted and non-trusted code. Bluetooth® LE work on Balletto B1, including an Auracast™ broadcast-audio demo application. Power optimisation down to sub-microampere current in low-power states, covering the full firmware power path.
From Model to Microamps: Edge AI That Fits a Battery
Running a neural network on an MCU is the easy part. Keeping it within the memory, compute and power budget of a battery-powered device is where most projects stall.
We take a trained model through Vela compilation, choose CPU or Ethos™-U execution per operator, and build it into firmware that sleeps at sub-microampere current between inferences. The result: wake-word, audio and vision features that run locally on Alif Ensemble® devices without draining the battery.
