    The Texas Instruments TMDSEZ28335 eZdsp starter kit is a complete software development platform for the TMS320F2833x series of floating-point Digital Signal Controllers. The eZdsp kit includes an F28335 target board that features integrated JTAG emulation, 128Kx16 asynchronous SRAM, CAN 2.0 and RS-232 interfaces, and expansion headers that provide access to all F28335 I/O signals. Also included in the kit is the Code Composer Studio™ Integrated Development Environment, USB interface to the host PC, and a universal power supply. This single orderable part number supports all regions of the world.

    The F28335 is a floating point signal controller, running at 150MHz. The F28335 eZdsp is suited for high-precision control applications. This board is, allowing the DSP to be changed to any F2823x (fixed point) or F2833x (floating point) device.

    The C28x+FPU is a 32-bit fixed-point processing unit with IEEE 32-bit floating-point format support. This CPU draws from the best features of digital signal processing; reduced instruction set computing (RISC); and microcontroller architectures, firmware, and tool sets. The C28x devices features include a modified Harvard architecture and circular addressing.

    The RISC features are single-cycle instruction execution, register-to-register operations, and modified Harvard architecture. The microcontroller features include ease of use through an intuitive instruction set, byte packing and unpacking, and bit manipulation. The modified Harvard architecture of the CPU enables instruction and data fetches to be performed in parallel. The CPU can read instructions and data while it writes data simultaneously to maintain the single-cycle instruction operation across the pipeline. The CPU does this over six separate address/data buses.

    Key Applications: Digital power, Digital motor control, Renewable energy, Power line communications, Lighting,Automotive, Precision sensing and control.
