Abstract
A novel and useful apparatus for and method of a unified IO controller well suited for use in integrated wireless devices incorporating multiple functions. The unified IO controller is operative to provide a single host interface PHY/MAC that is shared among all functions on the controller. The invention provides an IO protocol handler comprising common and unified logic that provides IO access to any function on the device. The common and unified IO PHY interface logic is shared between multiple functions within the same device (e.g., WLAN, GPS, Bluetooth, etc.). This implementation provides optimized hardware partitioning in which common SDIO logic serves multiple functions thereby eliminating the need to provide a protocol handler for each function, reducing pin count, power consumption and die size, since the SDIO protocol handling is implemented in a shared module.
