Crossware Develops USB BDM Debugger for Coldfire.Business Editors/High-Tech Writers CAMBRIDGE, England--(BUSINESS WIRE)--March 30, 2004 Crossware (www.crossware.com), a leading embedded software Instructions that permanently reside in a ROM or flash memory chip. Embedded software may be immediately available to the CPU or, for faster execution, may be transferred to RAM first and then executed. tools developer, has developed a USB USB in full Universal Serial Bus Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. BDM BDM Black Divorced Male BDM Business Development Manager BDM Background Debug(ger) Mode BDM Bund Deutscher Mädel (League of German Girls during the Third Reich, akin to Hitler Youth) (background debug To correct a problem in hardware or software. Debugging software means locating the errors in the source code (the program logic). Debugging hardware means finding errors in the circuit design (logical circuits) or in the physical interconnections of the circuits. mode) debugger for Motorola's ColdFire(R) family of chips. The USB debugger provides significant advantages over a parallel port BDM interface by ensuring that the data transfer rates from the PC to the debugger are super fast. In addition, advanced synchronization techniques have been used to optimize the data transfer from the debugger to the target board. Crossware has developed the small yet powerful and fast BDM debugger using the C8051F320 microcontroller A single chip that contains the processor (the CPU), non-volatile memory for the program (ROM or flash), volatile memory for input and output (RAM), a clock and an I/O control unit. from Cygnal (now part of Silicon Laboratories), which features a USB controller and requires no external crystal. The miniature debugger plugs directly into the target board minimizing signal delays and ensuring that it will be compatible with the next generation of ColdFire chips running at up to 200 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. . The USB debugger is driven by new version of Crossware's source level debugging software, which integrates seamlessly with the rest of its ColdFire Development Suite. The user interface is unchanged and so developers can simply replace their existing parallel port interface with the new USB debugger and immediately benefit from the improved performance. In addition, developers can also move to platforms such as the newer generation of notebook PCs, which do not have a parallel port. The debugger evolved out of a new version of Crossware's 8051 Development Suite. This version featured Code Creation Wizards to allow the USB controller and other peripherals of the C8051F320 to be rapidly configured.
