Processor for Internet of Things applications Skill sets used Algorithms and mathematics, Processor architectures, RTL and semiconductor IP , Software engineering, Business advantage The Challenge IOTA Computing had developed a low-cost low-power microprocessor for use in'Internet of Things' applications. They sought our assistance in verifying their design. Our challenge was to come up with a sufficiently thorough set of test cases to prove that their design functioned correctly under all circumstances. Our Approach Argon Design proposed the use of directed random instruction testing. To implement this, we wrote a simulator of the processor and its instruction set in C. We also developed a system for producing randomly generated valid code sequences, which could be submitted to the C simu
