The Diamond Standard 106Micro CPU is the smallest 32-bit RISC controller based on an industry-standard architecture, designed for lowest area and lowest power. This cache-less controller is ideal for designers looking for a basic 32-bit controller, particularly for those migrating up from an 8- or 16-bit controller. It enables SOC architects to integrate an efficient CPU in their designs, with the added benefit of extremely quick time-to-market.

Although the Diamond 106Micro is extremely small, it employs a 5-stage pipeline so it can easily achieve 250 MHz in 130G process and up to 400 MHz in 90G process technology. By modelessly switching between 24- and 16-bit narrow instructions, it achieves a much higher code density than other 32/16-bit architectures.

The local, tightly-coupled instruction and data memory on the Diamond Standard 106Micro can be used to store performance-sensitive code and data, for example, to achieve high performance on interrupt handlers.

The Diamond 106Micro has an iterative, multi-cycle (non-pipelined) 32x32 multiplier that greatly enhances performance on arithmetic and DSP code. The processor uses a non-windowed 16-entry AR register file to keep area low and that potentially does better on applications that have very deeply nested function calls, since it never throws an exception.

The Diamond Standard 106Micro has a rich interrupt architecture with an integrated interrupt controller with 15 interrupts, and an integrated timer. This simplifies system design since no external hardware needs to be added for these functions.
