RMP: API Comparison (Windows vs RT)
Comparison of 2 APIs and their 2 variations: for windows and for real-time
The document compares the following four variations:
API | Variation | Description |
|---|---|---|
RapidCode | RapidCode | RapidCode for Windows |
RapidCode | RapidCodeRT | RapidCode for INtime RTOS |
RapidSequencer | RapidSequencerWin | RapidSequencer for Windows |
RapidSequencer | RapidSequencerRT | RapidCode for INtime RTOS |
Note: In this document, if we call out RapidSequencer, assume it applies to both variations.
Bytecode is generally slower than native code. This applies to RapidSequencer as well.
On an RTOS, the code synchronization mechanisms that allow for deterministic code execution also slow down the execution of code. That is to say that real-time code is slower than but more deterministic than non-real-time code and that RapidCodeRT and RapidSequencerRT are no different.
In the order of decreasing speed/processing throughput:
- 1.RapidCode (for Windows)
- 2.RapidCodeRT
- 3.RapidSequencerWin
- 4.RapidSequencerRT
In order of decreasing determinism:
- 1.RapidCodeRT
- 2.RapidSequencerRT
- 3.RapidCode (for Windows)
- 4.RapidSequencerWin
Note: RapidSequencer is single-threaded, and execution processes one statement per task per cycle. This means that if you wait for an event to happen or for some time to elapse, the runtime will wait for that condition to be met, finish executing other tasks, which could take time, then execute the waiting task.
Variation | Requirement(s) |
|---|---|
RapidCode | - Requires using Visual Studio (or an IDE of choice) and correctly configuring headers and runtime libraries. |
RapidCodeRT | - Requires the same as RapidCode but also installing the INtime SDK, configuring compilation and runtime libraries against the INtime runtime, and developing a true RTOS application. |
RapidSequencerWin | |
RapidSequencerRT | - Programmable using the IDE provided by the RapidSetup tool.
- Requires further network configuration for the INtime node. |
In order of increasing complexity (easier to harder):
- 1.RapidSequencer
- 2.RapidSequencerRT
- 3.RapidCode (for Windows)
- 4.RapidCodeRT
Variation | Requirement(s) |
|---|---|
RapidCode | - Windows 10 - MSVC 2015/2017/2019/2022 runtime - INtime Runtime (6.4 or newer) |
RapidCodeRT | - Same as RapidCode- Additional INtime node (requires multi-node runtime) |
RapidSequencerWin | - Same as RapidCode |
RapidSequencerRT | - Same as RapidCode |
