	There is a large gap between ARM Cortex M4F and M7 and the next stop of Application SoCs. Although Application SoCs have the processing and superfast interconnect that will be beneficial for heterogeneous FPGA-MCU computing, the complexity of their packages is a very large step up from MCU-level packages and design complexity. At this point, without further research, it appears that there is no middle ground between affordable, easy, small, simple MCUs and SoCs that target SBCs and cellphones, etc.		There is a large gap between ARM Cortex M4F and M7 and the next stop of Application SoCs.

Lack of ARM Cortex M7 offers in ANY format (individual IC, core, heterogeneous solution, etc) beyond STMicroelectronics, Microchip, and NXP is particularly concerning. We don't know whether that is due to slowness of uptake, or due to manufacturers trying to overstep M7 and jump to an applications core...
