Method and apparatus for configuring an interface controller wherein ping pong FIFO segments stores isochronous data and a single circular FIFO stores non-isochronous data |
摘要 |
Hardware Description Language (HDL) code is created for an interface controller so that logic requiring device-specific configuration refers to a parameter file. This set of parameters lets components in a bridge circuit provide support for the same configuration. In another aspect of the invention, a control circuit identifies isochronous endpoints and non-isochronous endpoints. A buffer is configured into a first FIFO mode for isochronous endpoints and configured into a second FIFO mode for non-isochronous endpoints.
