IDT79R3051/79R3052 INTEGRATED RISControllers
COMMERCIAL TEMPERATURE RANGE
• Sable, an instruction set simulator.
• The IDT Laser Printer System board, which directly drives
a low-cost print engine, and runs Microsoft TrueImage
Page Description Language on top of PeerlessPage Ad-
vanced Printer Controller BIOS.
• Optimizing compilers from MIPS, the acknowledged leader
in optimizing compiler technology.
• IDT Cross development tools, available in a variety of
development environments.
• Adobe PostScript Page Description Language, ported to
the R3000 instruction set, runs on the IDT79R3051 family.
• The high-performance IDT floating point library software,
which has been integrated into the compiler toolchain to
allow software floating point to replace hardware floating
point without modifying the original source code.
• The IDT Prom Monitor, which implements a full prom
monitor (diagnostics, remote debug support, peek/poke,
etc.).
• An In-Circuit Emulator, developed and sold by Embedded
Performance, Inc.
• The IDT Evaluation Board, which includes RAM, EPROM,
I/O, and the IDT Prom Monitor.
