We developed an Impulse-Based Asynchronous Serial Address-Event Representation (IB-AS-AER) protocol. It allows for full-duplex communication and explicit flow control, does not require any clock data recovery or accurate clock relationship between the transmitter and receiver. Moreover, the optical fiber communication link, that galvanically isolates the communicating devices, highly improves the robustness to electromagnetic disturbances, reduces the power consumption and allows for high data rate transmissions. In addition, the proposed implementation does not require any specific hardware and can be developed on low-cost FPGAs as well as on full-custom ASICs. Preliminary tests performed at 100 Mbps raw bit transfer rate confirm a 32 bit maximum event rate of 2.9 Meps.

Abstract
We developed an Impulse-Based Asynchronous Serial Address-Event Representation (IB-AS-AER) protocol. It allows for full-duplex communication and explicit flow control, does not require any clock data recovery or accurate clock relationship between the transmitter and receiver. Moreover, the optical fiber communication link, that galvanically isolates the communicating devices, highly improves the robustness to electromagnetic disturbances, reduces the power consumption and allows for high data rate transmissions. In addition, the proposed implementation does not require any specific hardware and can be developed on low-cost FPGAs as well as on full-custom ASICs. Preliminary tests performed at 100 Mbps raw bit transfer rate confirm a 32 bit maximum event rate of 2.9 Meps.Pubblicazioni consigliate
