DSP Tool Suites

TASKING Inc.s of tool suites for Motorola's DSP56xxx and Infineon's CARMEL platforms have been announced that provide the increased functionality and efficiency to address the demands of embedded communications. The tool suites, which include Embedded Development Environment (EDE), C compiler and CrossView Pro debugger, now feature memory bank management, startup code options, quick display of variable information as well as numerous compiler and assembler optimizations.

The DSP56xxx Tool Suite eases migration from the GNU tools challenged by communications tasks, by linking COFF files containing relative branches. The DSP56xxx compiler optimizations achieve up to a 20% improvement in floating-point performance, while debugging capabilities pinpoint performance issues, speeding resolution of problems. The CrossView Pro debugger offers the ability to commandeer one of the timers to count instructions/cycles and to single step without stopping if an interrupt occurs.

The CARMEL tool suite supports compiler optimizations, language extensions for DSP applications, and the configurable long instruction word technology of the CARMEL DSP Core. The C-like assembler combines the performance of assembly language with the ease of a C compiler, while offering low-level control with function-like instructions for math, procedures, program flow and hardware repeat instructions. Enhancements to the CrossView Pro debugger let developers examine pipeline stages, complex breakpoints and register groupings through both the cycle-accurate simulator and on-chip-debugging-support.
