Linux Optimization Kit

Optimize embedded Linux applications without replacing your Linux kernel or BSP

MapuSoft’s Linux OK™ (Linux Optimization Kit) combines application profiling, optimized code generation, and OS abstraction to help embedded developers reduce runtime overhead and improve application responsiveness.



Optimize performance

Reduce selected API, scheduling, and resource-management overhead



Manage resources efficiently

Use thread pooling, resource pooling, and configurable memory management.



Measure and validate

Profile application behavior and compare performance before and after optimization.



Preserve your platform

Retain your existing Linux kernel, BSP, and hardware while optimizing supported application components.

What Is Linux OK?

MapuSoft Linux OK combines a Linux/POSIX interface, OS Abstractor technology, application-OS profiling, and optimized target code generation. It configures runtime components around the OS services and resources an application actually uses, supporting both application-specific optimization and portability across supported environments.

Linux/POSIX application interface and native Linux integration
Application-OS profiling and profile-guided optimization
Application-specific optimized interface and runtime code generation
Configurable target and resource requirements
Thread and resource pooling
Tiered memory pools, shared memory, and common IPC interfaces
Scheduling/runtime controls and soft-reset recovery capabilities

Conceptual Linux Architecture

How It Works

Linux OK operates above the existing GNU C libraries, system-call interface, and Linux kernel. It is designed to preserve the existing kernel, BSP, hardware, and overall application architecture.

Key Optimization Areas

CPU efficiency and selected OS/API interaction overhead
Scheduling behavior, task switching, and user/kernel-mode transitions
Thread and OS-resource creation through pooling and reuse

Memory footprint and shared-memory data movement
Application initialization and boot-time resource overhead

Results depend on the application, workload, target hardware, and configuration. Linux OK does not guarantee a fixed performance improvement or hard-real-time behavior.

Linux/POSIX Portability and Native Integration

Linux OK provides a Linux/POSIX-oriented interface across supported environments. Applications can continue using native Linux services where appropriate, and supported native Linux threads can be adopted into the OS Abstractor environment. API availability and behavior depend on the Linux OK release and target configuration.

Embedded Linux, ARM64, and Yocto

Linux OK can be integrated with supported 32-bit or 64-bit Linux systems, SMP or UP configurations, ARM64 targets, Yocto-based builds, and cross-development toolchains. Integration depends on the specific kernel, BSP, compiler/toolchain, hardware, and Linux OK release.

Measure the Results

Evaluate Linux OK using the same target hardware, compiler, Linux configuration, workload, and test method for baseline and optimized runs. Depending on the application, measurements can include:

CPU utilization and application response time
API execution time, throughput, and thread latency

Task-switching and user/kernel-mode behavior
Resource utilization, memory footprint, and initialization/boot time

A proof of concept can include application/build assessment, integration, functional validation, baseline and Linux OK profiling, code generation, comparative testing, and a report of measured results, limitations, and remaining work.
