As a strategic partner of the seL4 Foundation and a member of the RISC-V Foundation, Xcalibyte works on developing and optimizing the seL4 microkernel, providing solutions for system vendors and ensuring the safe and efficient operation of seL4-based operating systems on RISC-V hardware.

With Xcalibyte’s full suite of development toolchains and solutions, you can develop high-quality products running seL4-based operating systems that run faster, save costs and accelerate time-to-market.

Maximize performance

Xcalcompile helps you optimize your code for RISC-V hardware. Xcalcompile has the best benchmark test scores and outperforms other RISC-V compilers.

Xcalibyte’s analysis solutions help you find performance bottlenecks through:

  • Hot functions and hot execution paths
  • Processor execution time by task, function and source code line (including assembly)
  • Identifying performance issues due to system resource allocation and contention
  • Identifying performance issues due to processor pipelining or memory access

Productivity improvements

Xcalscan is our integrated static code analysis tool and features industry-standard support such as MISRA, AUTOSAR and CERT and contains our built-in rules for robust execution of high-quality secure coding.

Our GDB-compatible debugger solution helps quickly identify and solve visualization and debugging problems for all aspects of seL4-based operating systems. It also supports:

  • Kernel and user modes
  • Multi-thread and multi-core
  • Shared resource, lock and semaphore analysis
