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

The Am2045 is made of 43 homogeneous 'Brics' laid out in a 5 by 9 grid to form 344 cores and 344 RAM units.

General layout:

• 43x Brics
  • 2x Computer Unit (CU)
    • 2x SRD 32-bit CPU
    • 2x RD 32-bit CPU
  • 2x RAM Unit (RU)
    • 4x 2 KB SRAM bank

Cache[edit]

The Am2045 contains 43 Brics, each with its own RAM Unit (RU) of 13 kB of SRAM for a total of 559 kB of SRAM.

Memory controller[edit]

Expansions[edit]

• PCIe
• JTAG
• 128x GPIO @ 100 MHz
• serial flash
