Make the signal chain more intelligent and efficient with mixed signal processing and in memory computing
Hongjie LIU
Founder and CEO, Reexen

The traditional signal chain does majority signal processing after digitization which has the AD conversion bottle neck. The area and power on the AD dominates that of the whole analog front end.

The power and latency cost brought by data transfer between processing unit and the cache/dram also dominates that of the who digital processing part.

Reexen’s innovative architecture breaks down signal processing to mixed signal low level feature extraction before digitization and mixed signal high level in memory computing after digitization.

Reexen’s product can offer 1-2 orders improvement on energy consumption and 2-5 times cost improvement.
