Microprocessor and Bus-Specific Interfaces
There are a number of microprocessor and bus-specific interfaces
available as optional accessories which are listed in Microprocessor
and Bus Interfaces and Software Accessories for HP Logic
Analyzers. Microprocessors are supported by Universal Interfaces or
Preprocessor Interfaces, or in some cases both.
Preprocessor interfaces are aimed at hardware turn-on and
hardware/software integration, and will provide the following:
• All clocking and demultiplexing circuits needed to capture the
system’s operation.
• Additional status lines to further decode the operation of the CPU.
• Inverse assembly software to translate logic levels captured by the
logic analyzer into microprocessor mnemonics.
• Bus interfaces to support bus analysis for HP-IB, RS-232-C, RS-449,
SCSI, VME, VXI, ISA, EISA, MCA, FDDI, Futurebus+, JTAG, SBus,
PCI, and PCMCIA.
Universal Interfaces are aimed at initial hardware turn-on, and will
provide fast, reliable, and convenient connections to the
microprocessor system. Universal Interfaces do not provide inverse
assembly of software instructions.
