MicroTCA has found many uses in applications requiring a modular open standard that is smaller and cheaper than AdvancedTCA. Although MTCA.4 has closed the functional gap between ATCA and MicroTCA, the system and slot costs still are key to success, especially for smaller systems. A new hardware concept utilizing the capabilities of the MCH slot in a MTCA.4 system addresses this issue and helps to build more cost efficient solutions without degradation of the performance. At the same time this new hardware concept allows the customer to select from an even larger ecosystem of solutions than what was available so far. This presentation introduces new possibilities of MTCA.4 system configuration and presents first evaluation of the data transfer performance. To optimize performance of the system (in terms of data transfer bandwidth and latency) each configuration requires different approach on firmware/software layer. The presentation shows several concepts of data transfer implementation in PCIe environment and demonstrates their applications in an example uTCA system. Implementations include firmware level interfaces, driver to OS and interfaces to common control systems .
MTCA.4, RTM, more performance, cost saving, PCIexpress, EPICS and DOOCS

	MicroTCA has found many uses in applications requiring a modular open standard that is smaller and cheaper than AdvancedTCA. Although MTCA.4 has closed the functional gap between ATCA and MicroTCA, the system and slot costs still are key to success, especially for smaller systems. A new hardware concept utilizing the capabilities of the MCH slot in a MTCA.4 system addresses this issue and helps to build more cost efficient solutions without degradation of the performance.
