ARM and Handshake Solutions have released the creatively named ARM996HS processor, targeting very low power, very low EMI (electromagnetic interference) for embedded real-time applications. The big news is that the chip is "clockless."

By removing the clock and associated architecture of standard ICs,
clockless designs offer significant reductions in power consumption and
EMI enabling designers to squeeze more functionality into limited power
budgets. Handshake Solutions offers an extremely disciplined design
methodology that delivers the unique benefits of clockless design
within a commercially available design environment. The methodology is
supported by easy-to-use and thoroughly field-tested tools, design
services, and standard IP blocks from Handshake Solutions.

Target markets for this chip include implantable and wireless medical devices. This might also make an interesting processor for embedded component radios for medical devices.
