MAJC

(Microprocessor Architecture for Java Computing) Pronounced "magic," it was a CPU architecture from Sun for networked appliances. Originally the UltraJava CPU, MAJC was a multicore processor designed to support high-speed processing of music, video and other rich media. See Java chip.

The MAJC 5200 is expected to be able to handle over one hundred voice-over-IP channels while enabling encryption and decompression of the packets over a 10 gigabit-per-second Ethernet connection - so that large numbers of simultaneous phone conversations could be supported in a small-footprint gateway server device.
The first MAJC 5200 chip is expected to use .22 micron, six layer copper process and have a clock frequency of 500 MHz.
When MAJC was announced at the beginning of August, Sun's chief scientist Bill Joy told ComputerWire that the architecture was in "a different performance class" from rival chips such as National Semiconductor Inc's recently announced Geode line.
However - from what we know about MAJC - it has some key similarities.
The analyst described the Sun architecture as similar to a superscalar design, except that the MAJC compiler would be handling the chip's instruction scheduling rather than it being done in hardware.
However, Ken Tallman, senior product manager for the Java3D API, confirmed that his developers had been working closely with the team that developed the MAJC chip architecture.
The concept of the MAJC design is simple - multiple high performance processor cores on a single die - which can be programmed in a Java environment.
MAJC chips, Tremblay said, would allow for creation of a "service portal in your home." However, neither he nor O'Neal would be drawn on exactly what this meant.
