As Chips Reach Speed Limit, Makers Tap Into ‘Clockless’ Logic
January 9, 2002 | Source: International Herald Tribune
A worldwide community of private and academic researchers are perfecting a kind of lateral-thinking, anarchic method of chipmaking based on asynchronous logic, which does away with the clock altogether. Clockless chips, in addition to being more energy efficient, can also work faster, more quietly and more securely than synchronous chips. All of which makes them perfect for applications such as computer networks, mobile phones, smart cards and embedded medical devices.
Where the synchronous processor waits for a clock cycle to finish before starting the next task, an asynchronous one can do multiple tasks at different speeds.
