Single-chip edge devices (SCEDs) are small in size and low in power consumption.
They are especially suitable for smart nodes of Internet of Things (IoT) to form an edge
sub-cloud (ESC). Unfortunately, SCED's intensive computing ability is often unsatisfactory.
Therefore, we need to migrate cloud computing virtualization technology into SCED, and
manage its on-chip resources by cloud computing mode, so as to make its computing
capability more powerful. The focus of this research is how to set up the on-chip cloud
architecture of a domain general purpose integrated circuit (DGIC). The goal of this research
is to provide a DGIC solution for SCED, which owns both of CPU customizable semantic
processes and ASIC reconfigurable syntax elements. The cooperation of multiple SCED
devices can form a strong edge sub-cloud ESC. Its on-chip cloud architecture can ensure the
security and confidentiality of ESC. Based on the on-chip cloud structure of DGIC, we
fabricated and tested a SCED sample in the acceleration domain of multi-island genetic
algorithm. Its acceleration ratio was obviously better than the existing GPU + CPU approach,
which has the advantages of small in size and low in power consumption.
