Since the invention of the integrated circuit, many systems have been implemented by using IC, LSI and VLSI technologies. The design objective has been to realize systems which have high performance, high reliability, low power dissipation and low cost. Despite the rapid progress of semiconductor technology for microprocessors, logic, and DRAM, the integration of DRAM and processor has not been realized so far. This paper describes the implementation of a 32-bit RISC processor with embedded DRAM on one chip. This provides a high performance system component with low power dissipation, in other words, low processing energy components. In addition, this design provides the system designer with great flexibility. For example, JPEG decoding of full VGA can be realized in less than 0.5 sec by software using this chip, so that designers may eliminate the JPEG hardware module from a system.
