LinuxDevices.com: New system-on-chip runs native Java ... plus LinuxJun 08, 2000, 07:31 (0 Talkback[s])

"Imsys (Sweden) used the occasion of JavaOne 2000 in San Francisco to unveil an unusual new system-on-chip microprocessor that supports native on-chip Java bytecode execution -- but also runs embedded Linux. The device, called the Cjip, achieves a high degree of on-chip functionality via an unusual approach: dynamically alterable microcode."
"What's inside? Actually, it's difficult to say exactly what's in the device. That's because, unlike "normal" processors, its CPU employs semi-soft, rather than fixed, microcode. According to Imsys, two-thirds of the Cjip's microcode is fixed, while the remaining third is loaded on startup from an external ROM or Flash device. As a result, the instruction set is reconfigurable to match the requirements of a given application. Cjip has exploited that inherent flexibility by developing libraries of virtual peripherals, which Imsys calls "Veripherals...."
"The other supported software alternative is Linux. Since the Cjip supports multiple dynamically switchable instruction sets, it can be optimized for C or C++ based applications, in addition to Java. Based on this capability, Imsys has created an embedded Linux port, which is also freely available to support system designs based on the Cjip."
