I know Xilinx and Altera have their SoC devices which are a bit high end with dual A9 type ARMs. I recently found out the Microsemi SoC which uses a CM3 can be bought for just $16 and a KickStart board is available for just $59. I like it.
The FPGA fabric is flash based rather than SRAM so you don't need to configure it each time it powers up. The CPU has up to 512 kB flash and144 kB of SRAM. CAN, Ethernet and HS USB are included along with a number of simpler interfaces, DDR, SERDES and PCI3. Sounds like a pretty interesting device.
6k to 146k LUT4s, up to 240 math blocks and two sizes of block memory.
Anyone looking at using it? I'm thinking of getting the $59 board.
