upb
A small, fast C implementation of Protocol Buffers for embedded systems and high-performance applications.
What is upb?
μpb is a lightweight implementation of Google's Protocol Buffers serialization format written in C. It provides a minimal, high-performance alternative to the official protobuf library, designed specifically for resource-constrained environments where code size and speed are critical. The project enables efficient data serialization and deserialization for embedded systems and applications with strict memory requirements.
Embedded systems developers, firmware engineers, and C programmers working on resource-constrained devices who need efficient Protocol Buffers support without the overhead of the full library.
Developers choose μpb when they need Protocol Buffers functionality in environments where the official implementation would be too large or slow, offering a specialized solution that prioritizes minimal code size and maximum performance for embedded applications.
