Latest Patents

Fujioka's latest patents include an instruction decode method and arrangement suitable for a high-speed microprocessor. This innovative arrangement features a high-speed PLA decoder of small capacity for decoding instruction words with small execution cycles, alongside a low-speed PLA decoder of large capacity for decoding instruction words with larger execution cycles. The design allows for the activation of the low-speed PLA decoder when the high-speed decoder is not permitted to execute instruction decoding. This approach mitigates instantaneous current noises generated in the PLA decoders, preventing erroneous operations while maintaining high-speed microprocessor performance. Another significant patent involves an emulation method that allows programs to run on systems with different instruction word sets. This method minimizes overhead by translating input/output macro instructions from an emulated program into those compatible with the operating system.
