Working principle

The YSDKS3A7E20 evaluation board is based on a single-chip design, which integrates a Cortex-A7 processor core and a complete FPGA fabric. It also includes an on-chip bus and peripheral device support, 32KBytes RAM, 16MB SPI flash for storage, 5 megabit SRAM, dual UARTs, CAN bus, Ethernet, Wi-Fi, and Bluetooth. This allows the board to operate independently as stand-alone embedded applications or in conjunction with other boards or external control devices.

The Cortex-A7 processor core is the main computing element of the board. It has a maximum clock frequency of 1.5 GHz and can run up to four software threads concurrently. A 4MB L1 cache is available to support the processor core, and there is a 4MB L2 cache shared across the FPGA fabric. The FPGA fabric consists of four independent programmable regions, which can be used to implement custom logic, microprocessor support functions, and I/O peripheral interfaces.

The evaluation board also includes a 32-bit microcontroller unit (MCU), which runs on an independent clock from the processor core. It acts as an asynchronous controller for input and output devices, providing a direct interface to external sensors, actuators, and other devices. The MCU is also responsible for the communication between the processor core and peripherals via an on-chip bus or Ethernet.

The board offers a wide range of development and debugging tools, which includes a development environment, multiple compilers, and an integrated debugging environment. A demo application and sample applications are provided to help developers get started quickly.

The evaluation board is ideal for prototyping low-cost, low-power embedded systems with high performance and easy scalability. It can be used for a variety of applications in the MCU, DSP, automotive, consumer electronics, robotics, and industrial fields.
