Abstract
Systems are provided for the offloading of protocol control and conversion information within microprocessor-based systems. A converter controller comprises a first interface and protocol, as well as a second interface and protocol. An intermediate protocol and interface is interconnected to both the first protocol and the second protocol, and forwards or offloads protocol information to the system CPU, which comprises device driver information for protocol conversion and/or control. The CPU acts upon the received protocol information, performs protocol conversion as necessary, and forwards the converted protocol information back to the converter controller through the intermediate interface. Some embodiments of the offloading protocol conversion system comprise a SDIO controller within a USB-based device.
