We developed and put into the market an electronic tide calculator so called "Fishing Master", as an item of the Sports Watches Series. Fishing Master calculates future and past tides in height as wel1 as in time of occurrence, and provides information about the specific fishing spots. This information can be called out on the display by a simple operation. Fishing Master is designed also Compactly to fit in a shirt pocket. A 4-bit low power CPU controls the tide processing unit which consists of a 8-bit CPU, a 256k-bit ROM, a 16k-bit SRAM, and an address decorder. The dual-CPU system greatly reduces power consumption of the whole instrument.
