Input: Passage: In 2006, IBM launched Secure Blue, encryption hardware that can be built into microprocessors. A year later, IBM unveiled Project Big Green, a re-direction of $1 billion per year across its businesses to increase energy efficiency. On November 2008, IBM's CEO, Sam Palmisano, during a speech at the Council on Foreign Relations, outlined a new agenda for building a Smarter Planet. On March 1, 2011, IBM announced the Smarter Computing framework to support Smarter Planet. On Aug 18, 2011, as part of its effort in cognitive computing, IBM has produced chips that imitate neurons and synapses. These microprocessors do not use von Neumann architecture, and they consume less memory and power.
Output:
How much did it cost for IBM to produce Secure Blue?
