    Short description

    Programmer Documentation

    The Baikal-S (BE-S1000) Programming Guide is intended for developers of system software or bare-metal applications.

    The set includes 26 volumes and describes the structure of the microprocessor as a whole (memory map, interrupt list, etc.) and the individual functional subsystems (DDR, USB, PCIe, etc.).

    For each functional subsystem is given:

    • A detailed description of the structure;
    • The purpose of the main blocks and interfaces, features of their functioning;
    • The description of the programmable registers and their fields;
    • Recommendations for software management of the subsystem.
