It was found that, ... (TODO: hier Ergebnisse).
However, there is still room for improvement in the software model or the comparison methodology, which will be the subject of future work.
Firstly, the developed software library and the implemented model are not yet a drop-in replacement for the real \aca{fimdram} implementation due to the custom communication protocol between the host processor and the \ac{pim} processing units to implement the mode switching and transferring of the microkernels.
Firstly, the developed software library and the implemented model are not yet a drop-in replacement for the real \aca{fimdram} implementation due to the custom communication protocol between the host processor and the \ac{pim} processing units, used to implement the mode switching and transferring of the microkernels.
For this, more detailed information is required from Samsung, as the exact interface of \aca{fimdram} is not described in the published papers \cite{kwon2021}, \cite{lee2021} and \cite{kang2022}.
To ease the currently error-prone microkernel development process, the software library could help the developer by providing building blocks that assemble the microkernel and simultaneously generate the necessary \ac{ld} and \ac{st} instructions to execute the kernel.
In addition, the current bare-metal deployment of the software cannot realistically be used to accelerate real-world \ac{dnn} applications.
Instead, \aca{fimdram} should be able to be used on a Linux system, which would require the integration of the software support library into a Linux device driver.
To take into account the special alignment requirements of the \ac{pim} data structures, this device driver must also carefully consider the virtual address translation of the Linux kernel, possibly making use of so-called \acp{hugetlb}, as the alignment requirements exceed the default page size of $\qty{4}{\kilo\byte}$.
For a better evaluation of the performance gains of \aca{fimdram}, it should be compared with real-world \ac{dnn} applications.
For a better evaluation of the performance gains of \aca{fimdram}, it should be also compared with real-world \ac{dnn} applications.
Effects such as the initialization overhead of \aca{fimdram} can only be evaluated in such an environment.
Furthermore, the integration of \aca{fimdram} should be extended to \acp{gpu} or \acp{tpu}, so that the comparison can be extended to the deployment of the real \ac{dnn} applications.
