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 will have 148 million transistors, 1088-ball FCBGA with a 1.092mm pitch, and come in a 37.5mm x 37.5mm package. This will also be Intel's first integrated x86 processor, chipset and memory controller since 1994's 80386EX.
