Objective Systems is proud to announce the release of version 7.3 of its ASN1C ASN.1 Compiler product.
ASN1C is an ASN.1 compiler (code generator) capable of generating C, C++, C#, or Java source code from Abstract Syntax Notation 1 (ASN.1) or XML Schema Definition Language (XSD) syntax.
One of the key new features in this release is support for the JSON Encoding Rules (JER) introduced this past year in the ITU-T X.697 standard. Support has been added for generating encoders and decoders in all supported programming languages.
In addition, support was added for 3GPP TS 24.501 NAS Protocol for 5GS. Although this is not an ASN.1 standard, the ASN1C compiler can be used to generate 3GPP layer 3 encoders and decoders that support these message types in the C language. An ASN.1 specification was developed that provides an approximation of the data structures in ASN.1. To work around the parts that can't be encoded or decoded using standard ASN.1 PER bit-wise operations, special control directives and custom code were used. The specification is available in our ASN1C NAS/RRC Add-on Kit.
The following other new capabilities have been added in this release:
- New compact libraries for PER and UPER encoding and decoding in C that reduce code size by as much as half.
- Support for Canonical Octet Encoding Rules (COER) in Java and C#
- Generation of build artifacts for the Maven or Gradle build frameworks
