IBM unveils world's smallest computer

IBM has unveiled the world's smallest computer - a device no bigger that a grain of salt. Presented at the company's Think 2018 conference in Las Vegas, Nevada, the unit measures just 1mm by 1mm but has the same processing power as the x86 chip that ran early Nineties IBM desktop computers. The microscopic "crypto-anchor" CPU is essentially an anti-fraud device, designed to be embedded within price tags and product packaging like barcodes, tracking and logging the movement of goods during shipping. "The world's smallest computer is an IBM-designed edge device architecture and computing platform that is smaller than a grain of salt will cost less than 10 cents to manufacture and can monitor, analyse, communicate and even act on data," the company said. "It packs several hundred thousand transistors into a footprint barely visible to the human eye and can help verify that a product has been handled properly throughout its long journey."
