The Hyperstone E1-32 represents a new class of microprocessors, combining a high-performance RISC processor with an additional powerful DSP instruction set and onchip microcontroller functions. The high output is not achieved by raw clock speed, but is due to a sophisticated architecture which combines the advantages of RISC and DSP technology. It offers a powerful set of variable length instructions. Programs for the Hyperstone E1-32 require less than half the memory size of most RISC µPs. Most instructions execute within one clock cycle. The fast multiply unit at high clock frequency makes it one of the fastest CPUs on the market with regard to DSP functionality. For many applications, the Hyperstone E1-32 makes the use of additional DSP chips obsolete.

Up to now, separate DSPs and CPUs have been necessary for a number of applications, in particular for multimedia and telecom designs. Such applications can finally be realized through just one Hyperstone microprocessor because a DSP unit is already integrated into the architecture. Since the Hyperstone RISC/DSP processors are based on a single-core architecture, there is no need to worry about how to combine the controller with the DSP and the peripherals. Additionally, the use of development tools and operating systems is much easier than with two-core solutions, even if they are implemented on a single silicon die.
