Abstract
The present disclosure is directed to an in-memory communication infrastructure for an asymmetric multiprocessing system without an external hypervisor, and includes one or more processors and one or more computer-readable non-transitory storage media comprising instructions that, when executed by the one or more processors, cause one or more components to perform operations including identifying data for transmission from a first instance to a second instance, writing, by the first instance, the data into a first ring of a shared memory, the first ring configured as a first transmit ring for the first instance, sending an inter-processor interrupt to the second instance to alert the second instance of the data written into the first ring, reading, by the second instance, the data from the first ring, the first ring configured as a first receive ring for the second instance, and transmitting the data to an application of the second instance.
