Cypress MoBL dual port used to have effective communication between the two processors simultaneously using the mailbox registers. MoBL dual port provides a way to interconnect processing elements with different clock frequencies, bus widths, I/O voltages.
Introduction
The Cypress Semiconductor MoBL® dual-ports provide an ultra low-power, high-bandwidth, flexible solution for the intercommunication of two processing elements.
The MoBL dual-port removes the necessity for processing elements to communicate with a protocol such as I2C, SPI or UART. In addition, the MoBL dual-port provides a way to interconnect processing elements with different clock frequencies, bus widths, I/O voltages, and at bandwidths in excess of 400 Mbit/s.
