SmartFusion-II

Altreonic announces integrated FPGA support for its multicore/manycore capable OpenComRTOS Designer on Microsemi’s SmartFusion-II.

Advanced chip technology has in the last decade reached a level of integration whereby complete systems can now be made available in a single package. Such Systems On a Chip (SoC) contains often multiple types of processor cores, each specialized for their function, but also smart I/O blocks, on chip networks, caches and program as well as data memory. Recent chips also add FPGA logic blocks.

Since 2005 Altreonic has developed a formally developed runtime system and development environment called OpenComRTOS Designer. Formally developed, it has a typical code size of 5 to 10 KB and supports systems in a fully scalable way. It transparently supports systems with heterogeneous processing nodes as well as heterogeneous communication mechanisms. This makes it suitable for networked, distributed systems as well as for on-chip many/multicore SoC. Board Support packages have been developed for example  for TI’s C6678 8-core multi-DSP, Intel’s 48-core SCC as well as for multicore ARM and PPC systems, often replacing traditional memory hungry POSIX-style RTOS.

Today, Altreonic announces integrated FPGA support, demonstrated on Microsemi’s SmartFusion-II. On this chip the user finds a 166 MHz ARM Cortex M3, DMA, I/O blocks and memory as well as a flash programmable FPGA logic. Traditional approaches will treat the FPGA as a co-processing block that is explicitly accessed using dedicated software running on the ARM. In OpenComRTOS tasks synchronise and communicate using so-called intermediate “hub entities” that fully decouple tasks allowing them to be anywhere in the network whereby OpenComRTOS takes cares of the inter-node communication.
