Simultaneous data transfers over peripheral bus using CDMA technique

The need for an efficient interconnect architecture has been caused by continued increase of the required communication bandwidth and concurrency of small-scale digital systems. The issue of applying the code division multiple access (CDMA) technique for data transfer over peripheral bus are discussed in this paper. The proposed technique represents an efficient interconnection solution for implementation in embedded systems based on low pin-count processing elements. Eight different system configurations, in respect to the number of transmitters and receivers, are realized at register-transfer level (RTL) using VHDL. The simulation results show that the communication bandwidth is scalable as the number of transmitter-receiver pairs increase.
