Board Features; Cpu; System Ram; I/O Interfaces - VersaLogic BayCat VL-EPM-31ECP Hardware Reference Manual

CPU

The EPM-31 uses one of three Intel 4th Generation Atom (formerly "Bay Trail") System-on-
Chip (SoC) processors:

E3845 (quad core)

E3826 (dual core)

E3815 (single core)
Each core contains a 512 KB L2 cache. These processors support Intel 64-bit instructions, AES
Instructions, Execute Disable Bit, and Virtualization Technology.
See the Intel Atom Processor E3800 Product Family Datasheet
the CPU.
