Abstract :
A SoC design for applications of OMA DRM 2 Agent in mobile phones is presented in this paper, which has been verified by Altera Stratix EP1S80B956C6 FPGA development board. Several design aspects, which include an embedded 32-bits RISC CPU and AMBAtrade bus system, a DRM Agent accelerator, a high-performance TRNG, several interfaces and reasonable hardware/software partition, making it very efficient for the OMA DRM 2 application. Based on SMIC 0.25mum standard CMOS technology, the proposed SoC platform can work under the frequency of about 76MHz, and the core circuit is 112k gates, making it suitable for low-cost design. Besides, memory protection unit is added to enhance the security. Therefore, the proposed SoC platform has a fine potential in application.
