To provide fault-tolerant, spread spectrum clock signals, a plurality of processing modules having respective spread spectrum control circuits are provided. Controlling entity definition data is received, wherein a controlling entity is configured to control resources using a control hierarchy. A LOCOS region is formed on a p-type layer in a surface area of the silicon substrate as device separation region by oxidizing part of the silicon substrate. The user places hisher finger on the SpO2 sensor of the card. The system then sends the bitstream data to a first core.
