Hotwright Inc. is a semiconductor intellectual property provider based in Beaverton, Oregon, renowned for their cutting-edge NoISA processor. The company is driven by the understanding that traditional ISA-based processors, with their fixed ALU and register files, might limit flexibility. Their innovative NoISA processor eliminates these constraints by leveraging a novel Hotstate machine, enabling customized performance tailored to specific hardware architectures without modifying the FPGA itself. This technology allows energy-efficient solutions, suitable especially for edge computing and IoT devices.
By integrating advanced microcode control, the NoISA processor redefines hardware flexibility, providing an adaptable alternative to fixed instruction set architectures. This solution is excellent for scenarios where traditional softcore CPUs might be impractical due to size or speed constraints. The processor exhibits versatility and power efficiency, making it a stellar choice for creating compact and fast controllers, state machines, and adapting behaviors dynamically under software control rather than hardware alteration.
Another hallmark of Hotwright's innovation is the Hotstate machine, a highly parameterized microcoded algorithmic state machine system, crafted using RTL but programmed in a C subset. This flexible system significantly enhances design processes by breaking tasks into manageable state machine systems, streamlining development efforts, and reducing resource consumption. Unlike conventional processor cores which can be restrictive due to their size and complexity, the Hotstate machine allows engineers to construct systems that exactly match their application needs, effectively improving performance by allowing tailored hardware control.
