The most basic design rules are shown in the diagram on the right. The first are single layer rules. A width rule specifies the minimum width of any shape in the design. A spacing rule specifies the minimum distance between two adjacent objects. These rules will exist for each layer of semiconductor manufacturing process, with the lowest layers ...
An RTOS that can usually or generally meet a deadline is a soft real-time OS, but if it can meet a deadline deterministically it is a hard real-time OS. [3] An RTOS has an advanced algorithm for scheduling. Scheduler flexibility enables a wider, computer-system orchestration of process priorities, but a real-time OS is more frequently dedicated ...

TI-RTOS is an embedded tools ecosystem created and offered by Texas Instruments (TI) for use across a range of their embedded system processors. It includes a real-time operating system (RTOS) component-named TI-RTOS Kernel (formerly named SYS/BIOS, which evolved from DSP/BIOS), networking connectivity stacks, power management, file systems, instrumentation, and inter-processor communications ...
As the RTOS kernel is identical for single or multi-processor nodes, supporting a multi-processor system requires only to write a small task level driver that can send and receives Packets. OpenComRTOS is made available in binary, source code and Open Technology licenses.
A simple version of rate-monotonic analysis assumes that threads have the following properties: No resource sharing (processes do not share resources, e.g. a hardware resource, a queue, or any kind of semaphore blocking or non-blocking ())
(example: if a resistor in a schematic had resistance=1000 (ohms) and the extracted netlist had the a matched resistor with resistance=997(ohms) and the tolerance was set to 2%, then this device parameter would pass as 997 is within 2% of 1000 ( 997 is 99.7% of 1000 which is within the 98% to 102% range of the acceptable +-2% tolerance error) )
In embedded systems, a board support package (BSP) is the layer of software containing hardware-specific boot loaders, device drivers and other routines that allow a given embedded operating system, for example a real-time operating system (RTOS), to function in a given hardware environment (a motherboard), integrated with the embedded operating system.
