Embedded Software Engineering
Full-stack firmware development from BSP bring-up to production-ready RTOS integration. Arm Cortex-M/A/R, RISC-V, AUTOSAR, Linux BSP, Edge AI, and IoT connectivity, delivered by engineers who build their own hardware.
What We Do
Embedded Software Services in India
Seven engineering disciplines covering the full embedded software lifecycle, from silicon bring-up through production firmware, compiler migration and over-the-air updates.
BSP & Board Bring-Up
Complete board support package development from silicon evaluation through production-ready firmware. Clock tree configuration, peripheral initialisation, memory controller setup, and driver integration for Arm Cortex-M, Cortex-A, Cortex-R, and RISC-V targets.
RTOS Integration
Production-grade RTOS integration and optimisation. Thread architecture design, priority inversion analysis, stack sizing, inter-task communication, and deterministic scheduling validation across RTX5, FreeRTOS, Zephyr, and ThreadX (Azure RTOS).
AUTOSAR Classic & Adaptive
AUTOSAR BSW configuration, RTE generation, complex device driver development, and MCAL porting. Both Classic Platform for deeply embedded ECUs and Adaptive Platform for high-performance compute nodes.
Linux BSP & Device Drivers
Embedded Linux BSP development, U-Boot customisation, kernel configuration, device tree authoring, and Linux device driver development for custom peripherals. Yocto/Buildroot build system integration.
Edge AI & ML Deployment
Deployment of trained ML models onto resource-constrained MCUs and MPUs. TensorFlow Lite Micro, CMSIS-NN optimisation, model quantisation, and inference pipeline integration for vision, audio, and sensor fusion workloads.
Bootloader & OTA
Secure bootloader design with firmware update capability, MCUboot, custom bootloaders, dual-bank update strategies, rollback protection, and over-the-air update infrastructure for connected devices.
Compiler Porting & Toolchain Migration
Migrating firmware from IAR Embedded Workbench or GCC to the Arm Compiler (armclang) and Keil MDK, keyword, pragma and intrinsic translation, IAR .icf and GCC .ld linker configs to Arm scatter-loading, C-library migration (newlib/MicroLib/Arm C library), build/CI integration, and proven functional equivalence with a MISRA re-check.
Have an embedded software challenge?
Our firmware engineers specialize in BSP bring-up, RTOS integration, and AUTOSAR, from architecture through production deployment.
Architecture Coverage
Silicon We Work With
GSAS engineers have hands-on experience across the full Arm Cortex family and emerging RISC-V platforms. We do not just write drivers, we design firmware architectures, optimise for real-time constraints, and deliver code that passes safety certification audits.
Toolchain
Tools We Use & Distribute
Every tool listed here is one we use in our own projects and distribute across India. We do not recommend tools we have not battle-tested.

Two Arm Keil MDK Webinars This Summer: DevOps and Edge AI for Indian Cortex-M Teams
Arm is running two free live Keil MDK webinars this summer: DevOps with Keil MDK on 23 June and edge AI with ModelNova Fusion Studio on 21 July. What Cortex-M teams in Bengaluru, Hyderabad, Pune, Chennai, Mumbai, and Delhi NCR should know, shared by GSAS, Arm's authorized partner in India.
AI Data Centers in India: Test, Measurement & Memory Boom
AI is a hardware supercycle. Every AI rack has to be designed, brought up, powered, fed with memory, and kept alive, and each of those is a test, measurement and memory problem. Here is the full engineering toolchain behind the AI data center, mapped to what Indian teams can buy today through GSAS.
Arm FuSa RTS in Production: MPU Isolation, Thread Watchdogs, and Safety Class API for Indian Medical and Industrial Firmware
Beyond the certification dossier: how Arm FuSa RTS actually works in production firmware. MPU-based spatial isolation, thread-watchdog patterns, and the Safety Class API that Indian medical-device, industrial-controls, and railway-signalling teams use to keep ASIL/SIL/Class-C designs running safely.
STL vs DCLS vs Split-Lock vs Hybrid Mode: Picking the Right Fault-Detection Strategy for Indian Safety Programmes
Four different fault-detection techniques cover four different parts of the ASIL spectrum on Arm safety silicon, Software Test Library, Dual-Core Lock-Step, Split-Lock (Cortex-R52), and Hybrid Mode (Hunter-AE / Hayes-AE). The decision framework GSAS gives Indian Tier-1 / Tier-2 automotive teams, anchored on Arm's published functional-safety solutions.
How Many Arm UBL Seats Do You Actually Need?: A Sizing Guide for Indian CI/CD Teams
How Arm User-Based Licensing actually sizes against your team: per developer identity, not per parallel CI job. A short guide for Indian engineering managers planning the UBL migration, talk to GSAS for the per-team sizing exercise.
Cortex-M CI/CD with csolution.yml + cbuild + GitHub Actions: A Working Pipeline for Indian Firmware Teams
A concrete CI/CD pipeline pattern for Indian Cortex-M firmware teams using the modern Arm CMSIS-Toolbox CLI (csolution + cbuild + cpackget) on GitHub Actions runners, UBL-licensed builds, vcpkg tool deployment, parallel build matrix, and the firewall + caching gotchas that catch most teams.
