The Power of Intellectual Property


D32PRO scalable & royalty-free 32-bit CPU

    The D32PRO is a royalty free, silicon proven, high performance soft core of a single-chip 32-bit embedded controller, with Floating Point Coprocessor. Thanks to its increased code density, the D32PRO meets power and size requirements of new connected devices. That’s why both power and performance of this IP Core predestine it as a real alternative for ARM Cortex M0/M0+/M1/M3 in the deeply embedded market and especially for emerging market of connected devices (IoT). Responding to continuing demands for less power drain in system-on-chip (SoC) designs, DCD has developed the instruction set aimed at reducing the size of system's instruction memory. The D32PRO is aimed at low-power always on/always listening systems and those with less demanding clock frequencies such as Bluetooth Low Energy. Nevertheless the core is perfect for embedded systems that require greater computational performance and system complexity by supporting dual- and multi-core systems as well as improved code density. DCD’s IP Core is fully customizable - it is delivered in an exact configuration to meet customer’s requirements. The D32PRO is offered with great variety of peripherals, like USB, SPI, LCD, HDLC, UART, Ethernet MAC, CAN, LIN, RTC and many more – ready to be implemented with the CPU. The D32PRO is delivered with fully automated test bench and complete set of tests, allowing easy package validation at each stage of SoC design.

    Comprehensible and clearly defined licensing methods without royalty-per-chip fees make use of an IP Core easy and simple.
    Single Site license option – dedicated for small and middle sized companies, running their business at one location.
    Multi Sites license option – dedicated for corporate customers, running their business at several places. The licensed product can be used in selected company branches.
    In all cases the number of IP Core instantiations within a project and the number of manufactured chips are unlimited. The license is royalty-per-chip free. There are no restrictions regarding the time of use. There are two formats of the delivered IP Core:

    •       Verilog RTL synthesizable source code called HDL Source
    •       FPGA EDIF/NGO/NGD/QXP/VQM called Netlist


    Several parameters of the D32PRO can be easily adjusted to requirements of a dedicated application and technology. The configuration of the core can be effortlessly done, by changing appropriate constants in the package file or using GUI. There is no need to change any parts of the HDL code.
