Introduction to RTOS Part 12 – Multicore Systems | Digi-Key Electronics

Running jobs in an RTOS on a multicore system can appear intimidating at. When writing programs that use even more than one core, many cpus have special architectures that you must keep in mind. We analyze the FreeRTOS port for the ESP32 (referred to as ESP-IDF) and just how to synchronize tasks on both cores.

The option to the challenge can be located right here: https://www.digikey.com/en/maker/projects/introduction-to-rtos-solution-to-part-12-multicore-systems/369936f5671d4207a2c954c0637e7d50

Code for this video clip collection (consisting of demos, services, and difficulties) can be discovered below: https://github.com/ShawnHymel/introduction-to-rtos

Configuring a multicore system can be divided right into 2 standards: crooked multiprocessing (AMP) and also symmetric multiprocessing (SMP). AMP needs a main core running an os to arrange jobs in other (second) cores. In SMP, the OS works on all cores, and also the scheduler is cost-free to draw jobs from a common listing.

ESP-IDF is the port of FreeRTOS for the ESP32, and also it sustains SMP. The ESP32 is a dual-core system (although, single-core variants exist). We look at exactly how the ESP32 design is set up and exactly how each core can access memory, resources, and also disturbs.

In ESP-IDF, we have the choice of pinning jobs to a core (to make sure that only that core may run a certain job) or setting a job to “no fondness” (to make sure that the job can run in either core). Using “no fondness” is easier to execute and also enhances CPU usage and also tons balancing without much initiative. It becomes hard to establish when specific jobs will certainly run, which makes forecasting target dates tougher. Because of this, lots of embedded developers like to pin tasks to cores, as it permits a higher degree of determinism.

We show exactly how to run tasks on either core in the ESP32 as well as established them to “no affinity.” Kernel things (e.g. semaphores, mutexes, and lines) work throughout cores with no modification, as the ESP32’s cores share memory.

Introduction to RTOS Part 12 – Multicore Systems | Digi-Key Electronics

Running tasks in an RTOS on a multicore system can seem daunting at first. Many processors have unique architectures that you must keep in mind when writing programs that use more than one core. We examine the FreeRTOS port for the ESP32 (known as ESP-IDF) and how to synchronize tasks on both cores.

The solution to the challenge can be found here: https://www.digikey.com/en/maker/projects/introduction-to-rtos-solution-to-part-12-multicore-systems/369936f5671d4207a2c954c0637e7d50

Code for this video series (including demonstrations, challenges, and solutions) can be found here: https://github.com/ShawnHymel/introduction-to-rtos

Programming a multicore system can be separated into two paradigms: asymmetric multiprocessing (AMP) and symmetric multiprocessing (SMP). AMP requires a primary core running an operating system to schedule tasks in other (secondary) cores. In SMP, the OS runs on all cores, and the scheduler is free to pull tasks from a shared list.

ESP-IDF is the port of FreeRTOS for the ESP32, and it supports SMP. The ESP32 is a dual-core system (although, single-core variants exist). We look at how the ESP32 architecture is configured and how each core can access memory, resources, and interrupts.

In ESP-IDF, we have the option of pinning tasks to a core (so that only that core may run a particular task) or setting a task to “no affinity” (so that the task can run in either core). Using “no affinity” is easier to implement and optimizes CPU utilization and load balancing without much effort. However, it becomes difficult to determine when certain tasks will run, which makes predicting deadlines tougher. As a result, many embedded developers prefer to pin tasks to cores, as it allows for a higher level of determinism.

We show how to run tasks on either core in the ESP32 as well as set them to “no affinity.” Kernel objects (e.g. queues, mutexes, and semaphores) work across cores without any modification, as the ESP32’s cores share memory.

Introduction to RTOS Part 10 – Deadlock and Starvation | Digi-Key Electronics

Starvation and deadlock are two common bugs that can occur in concurrent programming. Starvation happens when one one or more threads do not get a chance to run or do not get access to a shared resource because other (often higher priority) threads are hogging the CPU or resource.

The code for the Dining Philosophers challenge can be found here: https://github.com/ShawnHymel/introduction-to-rtos/blob/main/10-deadlock/esp32-freertos-10-challenge-dining-philosophers/esp32-freertos-10-challenge-dining-philosophers.ino

The solution to the challenge in the video can be found here: https://www.digikey.com/en/maker/projects/introduction-to-rtos-solution-to-part-10-deadlock-and-starvation/872c6a057901432e84594d79fcb2cc5d

Code for this video series (including demonstrations, challenges, and solutions) can be found here: https://github.com/ShawnHymel/introduction-to-rtos

We can avoid starvation by ensuring that higher-priority tasks yield the processor periodically to allow lower-priority tasks a chance to run. Additionally, the higher-priority tasks should make sure to release any shared resources they might have to allow lower-priority tasks access to them.

We can also implement a technique called “aging” in a high priority task or in the scheduler itself. Aging gradually increases the priority of any task that has been in the blocked state for some period of time. Eventually, the task will reach the same priority level as the high priority tasks that are hogging the CPU/resource, and the previously low-priority task will get a chance to run. After performing its required actions, the low-priority task will have its priority downgraded to its original level to start the aging process again.

In the video, we provide the classic “Dining Philosophers” as an analogy to demonstrate starvation and deadlock. Deadlock occurs when all tasks are waiting on each other for a lock (e.g. mutex or semaphore) and no task is able to continue execution. Deadlock can result in system-wide failure and should be avoided at all costs.

We also give two possible solutions to the Dining Philosophers problem, including assigning a hierarchy to the locks as well as using a mutex to control access to the locks.
