The hardware-specific parts are +usually provided by vendor-specific or device-specific libraries that are then +handled by some OsmoTRX glue code presenting a unified interface towards the +rest of the code by means of a _RadioDevice_ class. + +The common part includes the core TRX architecture as well as code for +implementing the external interfaces such as the TRX Manager UDP socket, +control, and VTY interfaces. + +The hardware-specific parts include support for driving one particular +implementation of a radio modem. Such a physical layer +implementation can come in many forms. Sometimes it runs on a general +purpose CPU, sometimes on a dedicated ARM core, a dedicated DSP, a +combination of DSP and FPGA. + +Joining the common part with each of the available backends results in a +different binary with different suffix for each backend. For instance, when +OsmoTRX is built with UHD backend, an _osmo-trx-uhd_ binary is generated; when +OsmoTRX is built with LimeSuite backend, an _osmo-trx-lms_ binary is generated. +Build of different backend can be enabled and disabled by means of configure +flags, which can be found in each subsection relative to each backend below. |
