Iroc Technologies has developed what it reckons is the first intellectual property (IP) core to handle soft errors caused by alpha radiation.
Based on the Sparc version 8 architecture, the IP contains protection elements for memory cells and logic. The core has been put into a test chip made by STMicroelectronics on a 0.25µm. It runs at up to 100MHz.
Dr Michael Nicolaidis, Iroc's chief technical officer, says the core has more than 98% soft error coverage and is cheaper to implement than designs based on traditional techniques that depend on duplicate processing elements.
Eric Dupont, CEO, added: "In developing this processor using a commercial standard-cell library, we have proven that our methodology is the first cost-effective solution to deal with the soft errors issue in commodity systems."
