A 32-bit RISC processor board for a frequency hopping radio

The authors present a low-cost, general-purpose 32-bit reduced instruction set computer (RISC) implemented using the Acorn RISC machine (ARM). This processor board is typical of a stand-alone system which can be utilized in a variety of applications. The monitor program was written in a high-level language in order to ease the inconvenience of programming the ARM. Its use as a pseudorandom sequence generator in a fast frequency-hopping radio receiver gives satisfactory results. Its general-purpose characteristics also allow the board to be used as the controller to a programmable digital FIR filter in the same radio receiver.<>
