A method for unidirectional communication between tasks includes providing a first task having access to an amount of virtual memory, blocking a communication channel portion of said first task's virtual memory, such that the first task cannot access said portion, providing a second task, having access to an amount of virtual memory equivalent to the first task's virtual memory, wherein a communication channel portion of the second task's virtual memory corresponding to the blocked portion of the first task's virtual memory is marked as writable, transferring the communication channel memory of the second task to the first task, and unblocking the communication channel memory of the first task.
