Am2045 (later renamed Am2045A), codename Kestrel, was Ambric's original flagship MPPA introduced in late 2006. This model was made of 43 Brics arranged as a grid of about 5x9, making up a total of 344 32-bit RICS-like cores operating asynchronously at 1-333 MHz. This model was later replace with Am2045B.
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 43 bric for 344 cores instead. Earlier models might have had only 42 brics at one point for 336 cores.
Architecture[edit]
- Main article: Am2000 § Architecture
