GA144 144-computer Chip

The GA144 is the most powerful chip we have created to date, with 144 F18A computers and capable of up to 100 billion operations per second. This chip is currently being fabricated as a pre production shuttle run, and based on results of testing during Autumn of 2009 it could go to production as early as the start of 2010.

The chip measures 4.7 x 4.5 mm in a 180 nm process. That size was chosen because it is the largest chip we can presently package in the 10x10 mm QFN-88. 104 pads border the chip (16 ground pads connect to the exposed die attach paddle; 16 power pads and 72 signal pads connect to the 88 pins on the edges of the package) and 8 rows of 18 computers fit inside.

Low power results from our computer (one node of an array) being asynchronous (unclocked). Low energy results when each of the 144 computers is executing instructions only when it actually has something to do. Spec sheets will be forthcoming. Meanwhile this list of features should prove impressive. Bill Muench composed a handy poster with much info.

GA144 has 88 pins. Pins are numbered counter-clockwise from upper left.

22 of the edge computers have one or more I/O pins, with specialized ROM; six of these are capable of being used to boot the chip after reset. The 96 interior computers, and the 26 edge computers that don't have I/O pins, all have the same ROM with five exceptions noted below. Any of the 144 computers may be used as compute engines, as wires to pass messages, or simply left fallow with minimal power leakage; the 22 edge computers with I/O pins are assigned nominal functions based on their ROM and I/O pads. These nominal functions are as follow, by three digit node number:
