In this contribution, we designed a serial port interface (SPI) suitable for embedded systems, especially for Bluetooth baseband. Proposed architecture is compatible for the APB bus in AMBA bus architecture. The 8-bit design of the SPI module is in charge of transferring the data and the instructions between the external devices and the coprocessors. We adopted the cyclic redundancy check method for the error correction. Also, we provided the interface for multimedia cards. The designed SPI module was automatically synthesized, placed, and routed. Implementation was performed through the Altera FPGA and well operated at 25MHz clock frequency.
