Template:mpu Am2045 (later renamed Am2045A) was Ambric's original flagship MPPA introduced in late 2006. This model was made of 42 Brics arranged as a grid of about 5x9, making up a total of 336 32-bit RICS-like cores operating asynchronously at 1-333 MHz.
Originally this chip was supposed to have 45 Brics, hence the '2045' which was supposed to have 360 cores. However the final model only had 42 bric for 336 cores instead.
