AVA Lite RTOS for Microchip PIC24 and dsPIC US$1,750.00

AVA Lite2
AVA Lite RTOS for Microchip PIC24 and dsPIC

A Lighter AVA which has powerful RTOS designed exclusively for Microchip's PIC24 and dsPIC microcontrollers.

AVA Lite is a slimmed-down version of AVA yet still very powerful. It uses AVA's innovative kernel and incorporates several of its powerful modules.

Note: The price on the upper right corner of this page is for the Seat License (single) only.

AVA Lite RTOS Microchip PIC24 and dsPIC Fundamental Tools

Task

A Task is an execution context. It is used to execute a sequence of instructions in a mutually exclusive context.

Event Group

An Event Group encapsulates 16 individual events. Each event is represented by a bit. An event can be used by your program to indicate when something has happened.

A task can either get or watch an event or combination of events. Both operations cause it to block if all the events are not set when invoked. Getting event(s) clears them after they are set. Watching events simply wakes up the task but does not clear the events.

Interrupt Queue

An Interrupt Queue is used to pass byte oriented data between an Interrupt Service Routine and a task, or vice versa, in a synchronized manner. It uses an event, from an Event Group, to indicate whenever a write operation is performed on the Queue. This allows a task to wait on the event and process its contents as soon as an ISR is done writing to it.

Semaphore

A semaphore is a general purpose synchronization primitive used in all Operating Systems. It can be used to protect a critical region or manage access to a resource.

Lock

A lock is a synchronization mechanism used to protect a resource from concurrent access. It also employs a Priority Inheritance protocol to reduce Priority Inversion. Priority Inversion is when a lower priority task is accessing a resource that a higher priority task is waiting on.

Memory Pool

A Memory Pool is a fixed memory block management mechanism. Allocating and releasing of memory blocks is performed in constant time and no extra overhead is required for each block of memory in the pool.

Pipe

A Pipe is a inter-task communication mechanism. It employs a First-In First-Out data structure. Each slot in the pipe is designed to store an address to a much larger memory block allocated from a memory pool. A write operation will block if no slots are available. A read operation blocks if the pipe is empty.

Synchronization Point

A Synchronization Point is a run-time synchronization mechanism. A task or group of tasks can wait on a Synchronization Point for another task to wake them up. It is used to control task execution.

Timer

A Timer is a cyclic timer that sets an event on every period.
