Overview of Actions Semiconductor

Actions Semiconductor Co., Ltd. (NASDAQ: ACTS) is one of China's leading fabless semiconductor companies that provides mixed-signal and multimedia SoC solutions for portable consumer electronics. Actions Semiconductor products include SoCs, firmware, software, solution development kits, as well as detailed specifications of other required components and the providers of those components. Actions Semiconductor also provides total product and technology solutions that allow customers to quickly introduce new portable consumer electronics to the mass market in a cost-effective way.


The MP3 and MP4 solutions must be flexible enough to meet the ceaseless innovation in the Consumer market. This MP3 and MP4 solutions must target current applications as well as future designs.

"Developing a MP3/MP4 SoC is full of challenges because the application is more and more complex and the customers' needs always change," said Mu Wu, Vice Manager of the System Design Department. Actions requires an extremely reliable and flexible prototyping system for the MP3 and MP4 solutions, so they can validate the design, program and software applications.

Such a large Altera FPGA board Actions purchased outside is more secure, because Actions's expertise is SoC design and Software development. Also Actions may face problems such as the capacity is not big enough, the speed is not fast enough or the board is not stable enough. Developing the FPGA hardware ourselves would have added at least 2 ~ 3 months to the SoC design cycle. They needed an off-the-shelf really high reliability and performance prototyping solutions in order to support ongoing SoC projects.

S2C Solution

Actions selected S2C's rapid SoC prototyping solutions based on a review of FPGA-based SoC prototyping products available. "Compared with other vendors, S2C's products and customer support impressed us. What's more, we like the fact that the Prodigy V5 Logic Module is so flexible and reliable. The S2C prototyping solution enables us to build our SoC prototype verification environment quickly. Therefore we decided to continually use S2C's Prodigy V5 Logic Modules and the latest Prodigy S4 Logic Modules for our MP3 and MP4 SoC prototyping. We use some boards for FPGA verification and the other boards are used or software developments," said Mr. Wu.

The structure of S2C prototyping solutions is really wonderful. Its flexibility enables us to develop MP3 and MP4 chips today and in the future. Especially the rich choices for interface accessories enable Actions to upgrade functions or applications much easier.

S2C's rapid SoC prototyping solution


  • Reduced overall design cycle to get to market first with innovative new capabilities

  • Used a combination of Xilinx and Altera TAI Logic Modules

  • S2C pre-and post-sales support helped in the success of this project

  • Optimized the performance of its MP3 and MP4 SoC

  • Will work with S2C on co-simulation and co-emulation on future projects


Within S2C's rapid SoC prototyping solutions, Actions can reliably build a MP3 and MP4 SoC prototyping in just hours rather than weeks or months.

S2C's rapid SoC prototyping solutions fill the gaps in our verification environment. S2C's prototyping solutions high capacity, reliable and flexible help us minimize the risk of hardware failure." said Mr. Wu. "We can now focus on the SoC design and software development. S2C's solutions really reduce the design cycles, costs and risks. Having an effectively reference design, we can quickly move to the MP3 and MP4 system validation. And we can get to the market first which gives us a significant competitive advantage. We look forward to building the long-term cooperation with S2C in other areas, such as co-simulation and co-emulation."
