CodeWarrior Development Tools 5.0 includes support for the DSP56800 family, a line of hybrid digital signal processors from Motorola that features microcontroller functionality and integrated flash memory. Version 5.0 of the CodeWarrior tools includes a new version of the CodeWarrior IDE as well as new features and enhancements to the debugger, editor, and project manager. Among the new features are support for flash programming, the option to debug the target chip within a JTAG chain, a command converter protocol, enhanced setting of hardware breakpoints, pragma interrupt handling, and reporting on pipeline dependencies in in-line coding. Version 5.0 also includes board-specific project stationaries and supports the following DSP56800 evaluation boards: DSP56F801EVM, DSP56F803EVM, DSP56F805EVM, DSP56F807EVM, DSP56F826EVM, DSP56F827EVM, DSP56824EVM. CodeWarrior Development Tools for DSP56800 5.0 is available now for $1,195.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
