{{Short description|Intel embedded system on a chip}} '''Tolapai''' is the code name of Intel's embedded system on a chip (SoC) which combines a Pentium M (Dothan) processor core, DDR2 memory controllers and input/output (I/O) controllers, and a ''QuickAssist'' integrated accelerator unit for security functions.<ref>{{cite web |title=Cnet News: Live from Hot Chips 19: Session 7, Networking |url=http://www.news.com/8301-10784_3-9763743-7.html |access-date=2007-12-31 |archive-date=2012-09-05 |archive-url=https://web.archive.org/web/20120905123604/http://news.cnet.com/8301-10784_3-9763743-7.html |url-status=live }}</ref>
== Overview == The Tolapai embedded processor has 148 million transistors on a 90 nm 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.<ref>[https://arstechnica.com/hardware/news/2007/08/intel-confirms-details-of-tolapai-a-soc-embedded-processor.ars Intel confirms details of Tolapai, a SoC embedded processor] {{Webarchive|url=https://web.archive.org/web/20120324093606/http://arstechnica.com/hardware/news/2007/08/intel-confirms-details-of-tolapai-a-soc-embedded-processor.ars |date=2012-03-24 }} Ars Technica, August 30, 2007</ref>
