In today's rapidly evolving technological landscape, the demand for FPGA devices is growing across industrial automation, smart grids, security monitoring, and automotive applications. These sectors are pushing for more advanced design processes and higher-performance electronic systems, which often result in increased hardware costs and longer time-to-market. As a result, design flexibility, device reliability, and cost-effectiveness have become key competitive factors among FPGA manufacturers.
Modern control systems require high performance, efficiency, and precision, with strict demands on response times and accuracy. While MCUs excel in managing numerous I/O interfaces and programmable memory, they are best suited for low-cost, low-power, and low-precision applications. However, their limited processing power restricts their use in more complex environments. On the other hand, FPGAs, with their inherent programmability and parallel processing capabilities, are ideal for mid- to high-end control systems. They perform tasks in pure hardware without consuming CPU resources, allowing for superior performance. The complementary strengths of MCUs and FPGAs have led to the rise of the MCU+FPGA architecture, which is becoming increasingly popular due to its flexibility and efficiency.
With the emergence of System-on-a-Programmable-Chip (SOPC), many FPGAs now integrate DSP or CPU functions. Leading FPGA manufacturers can incorporate both soft cores and popular hard cores such as PowerPC and ARM, enabling FPGAs to fully replicate the functionality of traditional DSPs and MCUs. Additionally, custom instructions can be added to embedded processors, accelerating specific algorithms and offering greater pin flexibility. This combination not only reduces costs but also simplifies the design process and speeds up product development.
Altera’s SoC technology has gained significant attention by integrating an ARM-based hard processor system (HPS) into its FPGA architecture. According to Xie Xiaodong, Altera’s Asia-Pacific Product Marketing Manager, half of Altera’s future FPGA products will include MCUs, marking a strategic focus area. The current SoC series has received positive market feedback, showing strong growth potential. These devices enhance system performance, increase design flexibility, improve reliability, and reduce costs.
One of the key features of Altera SoC is its broadband trunk interconnect, which allows seamless integration between the HPS and FPGA fabric. This tight integration provides 100-Gbps peak bandwidth for data consistency between the processor and the FPGA, eliminating external I/O paths and significantly reducing power consumption. With built-in error correction code (ECC) and memory protection, the system becomes more reliable against hardware or software errors.
Flexibility, ease of use, and cost-performance are crucial for customers when choosing FPGA solutions. Altera SoC leverages hardware advantages, system configuration options, and multiple memory controllers to deliver exceptional flexibility. Even in minimal configurations, designers can customize peripherals according to specific needs, making full use of the FPGA’s inherent flexibility. In terms of usability, Altera’s adaptive debugging function enhances ARM-compatible software development, improving visualization, control, and performance. For cost-performance, monolithic integration, PCIe controllers, and power sequencing ensure long-term system scalability and reliability.
Altera is also advancing its SoC technology using Intel’s 14nm FinFET process, aiming to deliver next-generation devices optimized for ultra-high-performance systems like military, telecommunications, cloud networking, and storage. These devices are designed to overcome existing performance and power limitations.
Beyond technology, Altera is focused on building a strong ecosystem. Partners like ARM, WindRiver, and QNX support the Altera SoC platform, enabling seamless hardware-software integration. Through collaborations and events in cities like Shenzhen, Shanghai, and Beijing, Altera shares cutting-edge solutions to promote the adoption of SoC FPGAs.
A well-developed ecosystem offers users access to comprehensive design resources, including custom IP from Altera or its partners. This allows for quick adaptation to changing interface standards and helps businesses stay ahead in the market. With over 7,000 SoC development boards sold, the benefits of this approach are clearly recognized.
In addition, Altera is expanding its operating system support, now including open-source and 12 commercial OS vendors, ensuring robust board support packages for mass production. This continued investment in ecosystem development ensures that customers have the tools and resources needed to succeed in an ever-evolving market.
