New Actel application note “Adding Custom Peripherals to the AMBA Host and Peripheral Buses” gives the overview of customizing Actel’s CoreMP7 microprocessor. It shows how to create CoreMP7 design within CoreConsole. The Actel CoreMP7 microprocessor is a soft-core implementation of the industry-standard ARM7TDMI-S™ and is optimized for maximum speed and minimum size in Actel flash-based [...]

Xilinx released the document which describes a digital camera reference design using a CoolRunner-II™ CPLD. The low power capabilities of CoolRunner-II CPLD devices make them the ideal target for portable, handheld applications such as digital cameras. The complete reference design is available for download in VHDL Code. The image sensor utilized in this digital camera [...]

Microchip released new application note “IrDA® Standard Stack for Microchip 16-Bit Microcontrollers”. Many members of Microchip’s families of 16-bit microcontrollers provide native IrDA standard support via their UART modules. This greatly simplifies the hardware design, which basically means that the microcontroller requires only Infrared Transmitter/Receiver. The app note gives an overview of three IrDA protocols: [...]

Microchip published new application note AN1094 “Bootloader for dsPIC30F/33F and PIC24F/24H Devices”. The bootloader for dsPIC30F/33F and PIC24H/24F devices is used to load and run an application on the target device. The bootloader consists of two applications: Target side bootloader application which must be programmed into dsPIC30F/33F or PIC24F/24H program memory prior to bootloader operation. Host [...]

In the new issue No.115 of the “Power designer” , Hector F. Arroyo, Sr. Field Applications Engineer, National Semiconductor illustrates techniques for powering FPGA-based designs. FPGA-based systems are becoming increasingly common. While many designers favor FPGA-based architectures for the flexibility of adding features or making modifications through code, designing an adequate power supply involves some challenges. First is [...]

Maxim published new application note which provides example hardware and software for interfacing the DS3231 with an 8051-type microcontroller. This application note demonstrates how to interface a DS3231 to an 8051-type microcontroller and provides example code showing basic interface routines. The microcontroller used in this example is the DS2250, and the software is written in C. [...]
