Tolapai
Encyclopedia
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

System-on-a-chip
A system on a chip or system on chip is an integrated circuit that integrates all components of a computer or other electronic system into a single chip. It may contain digital, analog, mixed-signal, and often radio-frequency functions—all on a single chip substrate...
