Guiliani:Features
From Guiliani
Guiliani is a C++ software framework enabling the creation of visually appealing, hardware and OS platform-independent GUIs for embedded systems.
Guiliani adopts the philosophy of write once, compile for & run on many different target hardware. Once a Guiliani application has been developed, it can run natively on supported target platforms. When using Guiliani, the usual development workflow is to design the application on a PC and target a set of embedded platforms for production release.
Minimum HW requirements
Criteria | Requirements |
---|---|
MCU | 100Mhz |
ROM | ~700kb for Guiliani without resources |
RAM | ~50kb for Guiliani without resources |
Compiler | C++ Compiler with exception Support |
Operating System | no Operating System required, but many supported |
Architecture overview
Guiliani is split into two layers, the Guiliani runtime engine, and a platform abstraction layer.

Guiliani in detail
ROM/RAM memory usage
The following list contains values for the memory-usage of Guiliani in different configurations. of course the actual memory-usage heavily depends on the used features and resources.
All values are determined using the following configuation:
* Renesas RZ/A2M * GNU Tools ARM Embedded 9.3.1.20200408 * release-build with -O3
Operating System (choose one) | Description | ROM | RAM |
---|---|---|---|
FreeRTOS | The code-size which is contributed by the operating system heavily depends on the function which are used by the application. Guiliani only uses the standard-function for memory-allocation, timer- and task-handling and peripheral-access. | 240kB | depends |
ARM mbed OS | The code-size which is contributed by the operating system heavily depends on the function which are used by the application. Guiliani only uses the standard-function for memory-allocation, timer- and task-handling and peripheral-access. | 200kB | depends |
Graphics-API (choose one) | Description | ROM | RAM (not including memory for loaded images and framebuffers) |
---|---|---|---|
eGML (incl. image-decoder-libraries jpeg and png-lib) | eGML can be used if no GPU-accelerated hardware is present. It is a pure software-rasterizer and can decode some image-formats by default. | 1080kB | 15kB |
D/AVE | D/AVE is a FPGA-backed hardware-accelerated Graphics-API with a wide feature-set. | 110kB | 10kB |
BLU | BLU can be used on platforms with very low ROM/RAM-capabilities. it features the basic primitives (Line, Rects) and basic blits for images. | 60kB | 10kB |
Font-API (choose one) | Description | ROM | RAM (not including memory for loaded fonts) |
---|---|---|---|
FreeType | Standard-library for font-rendering. Can read TTF and OTF-files. | 300kB | 21kB |
GlyphLib | Bitmap-based font-engine using special exported fonts for very small platforms. | 10kB | 1kB |
Guiliani-Features | Description | ROM | RAM (not including working memory) |
---|---|---|---|
Core-Packages (mandatory) | Includes every basic thing Guiliani needs to run. Resource-Management, Eventhandling, Intelligent Redraw, Timer- and Command-Processing... | 350kB | 11kB |
DataPool | The DataPool is used to exchange values between the application and the GUI. | 10kB | 1kB |
Streaming-Engine | Enables Guiliani to read and write objects into streams. This is used for loading and saving GSE-projects. | 120kB | 2kB |
Feature-Factory | All Guiliani-controls, commands, behaviours and layouters which are available to be used in an application. Ranges from 2kB for an Image to 50 for a ComboBox. By using a tailored factory only the features of Guiliani which are used in the GSE-project are included in the final binary. | 550kB | |
Animations | Various types of animations. | 40kB |
