Mattel the world's second largest toy maker in terms of revenue, after The Lego Group. In 2014, it ranked #403 on the Fortune 500 list. On January 17, 2017, Mattel named former Google executive Margo Georgiadis as CEO. Georgiadis stepped down as CEO of Mattel on April 19, 2018. Her last day was on April 26, 2018. Ynon Kreiz is now the new CEO of Mattel. The name Mattel is a portmanteau of Harold "Matt" Matson and Elliot Handler, the company's founders. Harold "Matt" Matson and Elliot Handler founded "Mattel" in 1945. The company sold picture frames, and later dollhouse furniture.
Interrupt handler interrupts are often provided, which exacerbates stack usage. A primary constraint on the interrupt handler in this programming endeavour is to not exceed the available stack in the worst-case condition, requiring the programmer to reason globally about the stack space requirement of every implemented interrupt handler and application task. When allocated stack space is exceeded (a condition known as a stack overflow), this is not normally detected in hardware by chips of this class. If the stack is exceeded into another writable memory area, the handler will typically work as expected, but the application will fail later (sometimes much later)
