In today's rapidly evolving industrial landscape, the demand for FPGA devices is growing across various sectors such as industrial automation, smart grids, security monitoring, and automotive applications. These industries are pushing for more advanced design processes and complex electronic systems, which have led to increased hardware costs and longer time-to-market. As a result, design flexibility, device reliability, and cost performance have become key factors in the competition among FPGA manufacturers.
Modern control systems require high performance, efficiency, and precision, placing higher demands on response times and accuracy. While MCUs excel in managing 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 scenarios. On the other hand, FPGAs, with their inherent programmability and parallel processing capabilities, are ideal for mid-to-high-end control systems. By performing tasks in pure hardware without consuming CPU resources, FPGAs deliver superior performance. The complementary strengths of MCUs and FPGAs have driven the development of hybrid architectures, making the MCU+FPGA combination increasingly popular.
The emergence of System-on-a-Programmable-Chip (SOPC) has further enhanced the capabilities of FPGAs by integrating DSP or CPU functions. Leading FPGA manufacturers now support both soft and hard cores, including PowerPC and ARM, allowing FPGAs to perform the roles of traditional DSPs and MCUs. Custom instructions can be added to embedded processors, enabling faster execution of specific algorithms and greater flexibility in pin configuration. This integration not only reduces costs but also simplifies design and accelerates product development.
Altera’s SoC architecture integrates an ARM-based hard processor system (HPS) within the FPGA fabric, offering excellent performance and widespread market acceptance. According to Xie Xiaodong, Altera’s Asia-Pacific Product Marketing Manager, half of Altera’s future FPGA products will include MCUs, marking a key focus area for the company. The current SoC series has shown strong market feedback and growth potential, enhancing system performance, design flexibility, and reliability while reducing costs.
A critical feature of Altera SoC is its broadband trunk interconnect, which enables high-throughput data paths between the HPS and FPGA architecture. This tight integration provides up to 100-Gbps peak bandwidth, ensuring data consistency without external I/O paths, thereby significantly reducing power consumption.
Flexibility, ease of use, and cost-performance are essential for customers when selecting FPGA devices. Altera SoC leverages hardware advantages, multiple memory controllers, and system configuration options to offer unmatched flexibility. Even in simple configurations, it allows designers to customize peripherals according to their needs, fully utilizing the FPGA’s 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 viability and scalability.
Looking ahead, Altera’s 10th generation devices will leverage 14nm FinFET technology, optimized for ultra-high-performance applications such as military, communications, cloud networking, and computing. These next-gen solutions aim to overcome existing performance and power limitations.
Altera continues to invest in ecosystem development, collaborating with leading partners like ARM, WindRiver, and QNX. These partnerships enhance silicon fusion, integrate hardware/software programmability, and provide flexible, cost-effective solutions. Through seminars and design collaborations, Altera promotes the adoption of SoC FPGAs across key markets.
With a rich ecosystem, users gain access to comprehensive design resources, including custom and pre-configured IP from Altera or its partners. This allows rapid adaptation to changing interface standards and helps capture market opportunities. Over 7,000 SoC development boards sold so far reflect the growing recognition of these advantages.
In terms of operating systems, Altera supports both open-source and commercial OS vendors, providing mass production-level board support packages. This ensures broad compatibility and seamless integration for developers worldwide.
