Kane Computing are pleased to announce the launch of the GDD7700 L7 MCU/DSP Real-time Operating System. The GDD7700 provides a real-time multitasking environment, which allows for concurrent process execution. It implements small memory footprint and fast process scheduling and dispatch. It also has API to handle hardware system events and supports real-time I/O Device Driver model. The RTOS supports multiple TI DSP and MCU devices, including multicore and DaVinci processors.
The RTOS can be easily integrated with TI Code Composer Studio IDE and Code Generation Tools or GCC/++ tool-chain. The internal binary format complies with TI’s C/C++ ABI/EABI calling conventions.
The RTOS supports a wide range of TI signal processor devices and GPU, including C64x/C64+, C67x/C67+, C647x, C674x, Key-Stone C66x, DA7/8, OMAP L-137/138, Integra C6A816x, DaVinci DM64x, DM644x, DM646x, DM816x, DM814x, Sitara ARM Cortex-A8/A15 (AM389x, AM387x, AM35x).
The user’s manual gives the details on using the RTOS.
An evaluation release of the RTOS is available to download now.
Features
PROCESS SCHEDULING
- Pre-emptive real-time multitasking
- Processes are scheduled using priority time-slicing algorithm
- Interrupt (hardware) priority (number of priorities depends on hardware interrupt controller), Driver priority (32 levels), Real-time Process Priority (32 levels), Background Process Priority (32 levels)
- Time-sliced Round-Robin scheduling algorithm at single priority level
- Driver scheduled until operation is complete, pre-emptive, interruptible
- Background processes scheduled using time-slice proportional to process priority
