Abstract

A connection circuit is setup between microprocessor such as X86, ARM, and MIPS etc. and chips in ACX100 series for the compatible interface. The connection circuit manufactured in build in type or interface card type includes a data unit, a bit addressing unit, a reset unit, a waiting unit, a chip selection unit, a write unit, a read unit and a interruptive unit. Based on operations and cooperation of the said units, the goals for accessing data and compatible between X86, ARM, MIPS etc. and chips in ACX100 series is reached.

Description

technical field [0001] The invention relates to a compatible interface device between an MCU and a wireless area network. Background technique [0002] see figure 1 As shown; the wireless network device A (for example: wireless network card, PCI interface or USB interface device, etc.) equipped with ACX100 series chip A2 is currently on the market. The ACX100 series chip A2 is embedded and supports ACX100 series chips The microprocessor A1 of A2 (for example: X86 series, ARM series, MIPS series, etc.) is all built-in embedded; and the process, function and compatibility of the microprocessor A1 are not the same due to the manufacturer's design, so when the When the microprocessor A1 and the ACX100 series chip A2 need to support each other, a circuit needs to be specially designed to make the microprocessor A1 and the ACX100 series chip A2 reach a compatible working state, and then the RF antenna A3 will Its data is converted into a signal, and the signal is sent to the wir...
