Zdenek Dokoupil

   This article describes a new interface (alternative way of serial communication) between a personal computer and several remote Motorola's digital signal processors DSP96002. An on-chip emulator serial port was used for fast loading and saving the contents of X, Y and P memories. A new host-bus interface board for controlling up to 5 target applications and utility programs were developed. The achievable speed of communication is up to 55 kword/s for saving and 24 k word/s for loading DSP memories (word = 32 bits).

Keywords: digital signal processor (DSP), on-chip emulator, ISA bus, PCI bus
