Nowadays, on-line testing is essential for modern microprocessors to detect latent defects that either escape manufacturing testing or appear during system operation. Small memories, such as L1 caches and translation lookaside buffers (TLBs) are not usually equipped with memory built-in self-test (MBIST) hardware. Software-based self-test (SBST) is a(More)
This PhD thesis introduces a low cost Software-Based Self-Test (SBST) fault detection methodology for small embedded cache memories. The methodology leverages existing powerful mechanisms of modern ISAs by utilizing instructions that we call in this PhD thesis Direct Cache Access (DCA) instructions. Moreover, our methodology exploits the native performance(More)
