Rabbit Semiconductor was formed expressly to design a a better microprocessor for use in
small and medium-scale controllers. The first product is the Rabbit 2000 microprocessor.
The Rabbit 2000 designers have had years of experience using Z80, Z180 and HD64180
microprocessors in small controllers. The Rabbit shares a similar architecture and a high
degree of compatibility with these microprocessors, but it is a vast improvement.
The Rabbit has been designed in close cooperation with Z-World, Inc., a long-time manu-
facturer of low-cost single-board computers. Z-World and Rabbit Semiconductor products
are supported by an innovative C-language development system (Dynamic C).
The Rabbit 2000 is easy to use. Hardware and software interfaces are as uncluttered and
are as foolproof as possible. The Rabbit 2000 has outstanding computation speed for a
microprocessor with an 8-bit bus. This is because the Z80-derived instruction set is very
compact and the design of the memory interface allows maximum utilization of the mem-
ory bandwidth. The Rabbit races through instructions.
Traditional microprocessor hardware and software development is simplified for Rabbit
users. In-circuit emulators are not needed and will not be missed by the Rabbit developer.
Software development is accomplished by connecting a simple interface cable from a PC
serial port to the Rabbit-based target system.
