Bus Blaster Low Cost Debug Adapter for MIPS Cores
Bus Blaster V3c for MIPS is an inexpensive, yet flexible debug adapter (probe) designed for supporting JTAG debug with M-class and I-class MIPS processors, as well as earlier cores, such as M4K, M14K, microAptiv UC/UP, PIC32, 24K, and others. The Bus Blaster has a 14-pin target connector and interface cable with buffering logic suitable for MIPS (E)JTAG targets.
Imagination software development and debug tools that can be used with the Bus Blaster, include the Codescape Debugger, Codescape for Eclipse IDE, Codescape Console, and Codescape Essentials SDK.
You have a number of debug interface options allowing use of the Bus Blaster with the ideal development environment for your project. Whether you are a beginner or experienced MIPS software developer, the Bus Blaster and MIPS development software can help you get your project completed faster and easier. And now there are no prohibitive costs for development tools holding you back.

Software Tools Overview
Imagination Technologies’ Codescape Debugger offers multi-core, multi-threading and many other features for debugging software running on MIPS SoCs. It is a multi-window environment with easy to use features such as drag and drop between views, built-in make manager, editable memory, real-time RTOS aware debugging and much more. Codescape Debugger offers many ways to customize its regions and views for your particular application.
The Codescape Console is a low-level Python script-based command-line interface. You can take advantage of the built-in command system with context help and command completion to access and control all target features, or you can build custom Python scripts for extensive automated testing and design verification (DV).
Codescape for Eclipse provides a complete integrated development environment with a rich third-party plugin eco-system. The Codescape Essentials SDK is the fundamental tool chain of GCC components, libraries and utilities for compiling and building programs. The Codescape Essentials SDK, Codescape Debugger and Codescape for Eclipse tools are all available as free downloads from the Imagination Technologies web site.
