The FPS6 is a fully 32 bit general purpose CPU featuring single precision floating point, designed to meet the needs of the most demanding embedded systems.
The FPS6 is a modern processor with a high throughput RISC core coupled with a floating point ALU to boost performance. It has a full Harvard architecture. The instructions are 16 bits in length, with a 16 bit extension when needed (no mode switches necessary) giving excellent code density. The pipeline features out-of-order execution enabling nearly all integer instructions to execute in a single cycle, including loads and stores. Interrupts are fully vectored and the architecture ensures a minimum of software overhead in task switches. The processor was designed to execute high level languages, notably C, with ease. The software application can be entirely realised in C, interrupt routines included. The entire GNU GCC toolsuite has been ported to this architecture.
