Online Stack Overflow Detection on the TMS320C28x DSP
PDF, 407 Kb, File published: May 2, 2003
A stack overflow in an embedded DSP application generally produces a catastrophic software crash due to data corruption, lost return addresses, or both. Traditional off-line approaches to sizing a stack during development, such as filling with a know value, or estimating based on code content, are not 100% reliable. Therefore, programmers often feel compelled to reserve larger stack sizes than are
