Tolapai

Tolapai is the code name of Intel's system-on-a-chip (SoC) embedded processor which combines an x86 processor core, DDR2 memory controllers and I/O controllers, and a QuickAssist Integrated Accelerator unit for security functions.

The Tolapai Embedded processor has 148 million transistors on a 65nm process technology, 1088-ball FCBGA with a 1.092mm pitch, and comes in a 37.5mm × 37.5mm package. It is also Intel's first integrated x86 processor, chipset and memory controller since 1994's 80386EX.
