This section provides a brief primer to the protocol used on the local bus common to the Alpha Data Xilinx Reconfigurable Coprocessor range. The key features of the local bus are:
The differences between the models in the ADM-XRC range can be summarized by the following table:
Feature | ADM-XRC ADM-XRC-P |
ADM-XRC-II-Lite | ADM-XRC-II ADP-WRC-II ADP-DRC-II |
ADM-XPL | ADM-XP ADP-XPI |
ADM-XRC-4LX ADM-XRC-4SX |
Max. local bus frequency | 40.0MHz | 40.0MHz | 66.67MHz | 80.0MHz (see note 1 below) |
80.0MHz | 66.67MHz |
Multiplexed address/data | No | No | No | Yes | Yes | No |
Supported data widths on local bus | 32 bits | 32 bits | 32 bits | 32 bits, 64 bits |
32 bits, 64 bits |
32 bits |
Local bus bridge | PCI9080 | PCI9080 | PCI9656 | Virtex-II | Virtex-II | PCI9656 |
Note 1: If logic revision from INFO utility is 1.2 or greater, max. LCLK frequency is 80MHz; otherwise 66.67MHz.
