IDE produces faster
more compact DSP code
The latest integrated development environment (IDE) and optimising compilers for LSI Logic's ZSP digital signal processors automate all aspects of embedded software development
The latest integrated development environment (IDE) and optimising compilers for LSI Logic's ZSP digital signal processors automate all aspects of embedded software development while producing the industry's fastest and most compact ZSP code. Available to ZSP developers free of charge on a 30-day trial basis, the Multi IDE from Green Hills Software is ideal for developing embedded software for multiprocessor systems that combine one or more ZSP processors with ARM, MIPS, or PowerPC host controllers.

By using the Multi IDE, together with Green Hills' compilers, engineers will be able to simplify and speed the development of complex signal processing applications that take full advantage of the ZSP's high-performance superscalar capabilities.
LSI Logic's ZSP is an advanced DSP, employing an orthogonal instruction set and superscalar design that enables designers to maximise performance and code density without having to master complex VLIW instruction sets.
The ZSP400 is a family of high-performance, synthesiseable, 16bit, superscalar DSP cores.
Featuring a peak performance of 800MIPS at 200MHz, ZSP400 cores can execute 400 million multiply-accumulate operations per second.
ZSP cores come equipped with two 16 x 16 multiply-accumulate units, two 40bit accumulators, and up to 1Mword of on-chip memory.

ZSP cores can also be embedded with ARM, MIPS, and other host processors, together with memory, LAN and WAN interfaces on a single device to produce a complete system on a chip.
Multi greatly simplifies the development and production of fast, compact code for the ZSP core, including multiple cores integrated on the same chip.
The IDE features a window-oriented editor, ZSP-optimised source-level debugger, graphical program builder, project manager, and run-time error checker.
In addition, Multi includes a version control system, performance profiler, and real-time EventAnalyzer.
An instruction set simulator that is fully integrated with LSI Logic's own cycle-accurate simulator supports advanced data visualization tools such as Matlab.
Multi's optimising C compiler takes full advantage of the ZSP's superscalar capabilities, employing software pipelining to keep the ZSP's two multiply-accumulators and ALUs operating at full speed.
The Multi IDE ZSP-optimised source-level debugger supports process- and system-level debug and provides a separate window for each process.
Mixed assembly and high-level language formats are supported and a language-sensitive expression evaluator is provided.
The debugger also features incremental debug capability and a graphical memory viewer.
The Multi debugger supports a variety of host/target connectivity options, including Green Hills' own high-speed emulation probe, the Green Hills Probe.
