Template:mpu Am2045B was Ambric's flagship MPPA introduced in late 2007. This model was made of 42 Brics arranged as a grid, making up a total of 336 32-bit RICS-like cores operating asynchronously at 1-350 MHz. This was an enhanced version of the original which featured a higher bandwidth network on a chip (Ambric claimed up to 40 percent improvement), operated at higher frequency, and provided up to 1.2 trillion operations per seconds theoretical peak computation. This model also had lower power consumption over the original.
