PICMG udvikler et mindre COM-HPC modul og annoncerer FuSa-support

I forbindelse med embedded world udstillingen annoncerede PICMG konsortiet to nye specifikationer relateret til high-end COM-HPC standarden, COM-HPC Client Mini og Fusa (in english).

PICMG – a leading consortium for the development of open embedded computing specifications – announces two new specifications for the high-end Computer-on-Module standard COM-HPC. They target mixed-critical functional safety applications and small form factor designs requiring credit card-sized modules.

Like COM Express Mini, the COM-HPC Client Mini specification will define the use of one connector instead of the two implemented for the larger modules (Sizes A -E). But with COM-HPC, half the number of signal pins still means 400 signal lanes, which equals 90% of the capacity that COM Express Type 6 modules offer.


Compared to COM-HPC Client Size A modules, the smallest available COM-HPC form factor, COM-HPC Mini, also reduces the footprint to 50%. Such extremely small modules measuring only 60 x 95 mm are required for high-end embedded computer logic in devices such as top-hat rail PCs for control cabinets in building and industrial automation, or portable test and measurement devices.

In addition, the new specification will enable engineers to integrate state-of-the-art computer interface technologies such as PCIe Gen4 and Gen5 into ultra-small processing units that provide highest performance. As the new specification will come with a focused high-performance pinout and will comply with the entire COM-HPC ecosystem, it is expected to become the high-end standard extending the PICMG's earlier COM Express Mini standard.

PICMG expects the COM Express specification to continue leading the COM market for many years as it meets numerous standard application requirements now to be allocated in the mid-range performance sector.

FuSa support added

The new version of COM-HPC defines signal pinouts to support FuSa (Functional Safety) applications. These applications include safety critical machine control, autonomous vehicles and robotics, transportation related hardware such as train and wayside control, avionic equipment and much more.

The new extensions for functional safety (FuSa) target an even more promising market: Connected device developers want to utilize x86 processor technologies to be able to execute mixed-critical applications on multi-core processors. This requires redundancy and the possibility of implementing fail-safe processes.

With the new functional safety extensions, COM-HPC is thus entering a market that is expected to accelerate the demand for embedded Computer-on-Modules significantly. Besides functional safety control applications that require an IoT and industry 4.0 gateway, it also targets collaborative robotics working closely with humans.

Further markets arise from the demands of automated intralogistics with autonomous logistic vehicles and stretch from factory mobility to any new market that can be found in autonomous driving, from agricultural and construction machinery to smart city vehicles and AUVs as well as UAVs. Of course, the functional safety extensions are supported across all COM-HPC form factors, including the upcoming COM-HPC Client Mini.

- With the small size definition of the COM-HPC Client Mini and the FuSa extensions, COM-HPC covers all embedded use cases I can think of. COM-HPC is the most complete computer module definition ever. I expect an extremely fast growth for scalable and compute-power hungry embedded applications based on COM-HPC technology, says Christian Eder, Chair of the COM-HPC technical committee and Congatec Director Product Marketing.

The FuSa specification in detail

FuSa versions of some contemporary chipsets or System-on-Chips (SoCs) incorporate a FuSa “Safety Island”. This is a specialty portion of the hardware – along with supporting firmware and software – that is separate from the main portion of the chipset or SoC.

The Safety Island monitors the health and status of the main chipset or SoC and can report any findings over a dedicated FuSa GPIO and dedicated FuSa SPI Slave interface to an external carrier based FuSa System Safe State Agent and optionally a Safety Controller. The FuSa 'Safety Controller'  is a carrier based microcontroller that collects safety and status information from the Safety Island over a dedicated SPI bus and processes it for external use. The Safety Controller is the FuSa SPI Master.

The efforts of both new specifications are sponsored by: congatec, Kontron and ADLINK.
