MULTISTAGE BOOT IMAGE LOADING BY CONFIGURATION OF A BUS INTERFACE |
| 摘要 |
An integrated circuit (IC) that includes a processor circuit can be booted by receiving, using a storage interface circuit of the IC, a first boot image from a nonvolatile memory chip. The first boot image is executed on a processor circuit of the IC to configure a bus interface module that is designed to communicate with a host device over a communication bus that links multiple devices and the IC. Using the bus interface module, a second boot image is received from the memory of the host device to a memory of the IC. The IC is booted by executing the second boot image. |

1. A method for booting an integrated circuit (IC) that includes at least one processor circuit, the method comprising:
receiving, using a storage interface circuit of the IC, a first boot image from a nonvolatile memory chip; configuring, by executing the first boot image on a processor circuit of the IC, a bus interface module that is designed to communicate with a host device over a communication bus that links multiple devices to the IC; communicating, using the bus interface module, a second boot image from a memory of the host device to a memory of the IC; and booting the IC by executing the second boot image. |
