PEPS-III
EPROM Simulator is a tool for designing control software ("firmware") for
micro- and mono-board computers respectively. During that process the
PEPS-III (Programmable EPROM-Simulator) is plugged into the EPROM
socket of the target system, takes over the EPROM's functions and
allows the user to quickly test software, as one would with a CPU
emulator . Some RAM types can also be simulated with the PEPS-III,
allowing the working storage area of the micro- or mono-board computer
to be read into the the PC. In this manner a post mortem debugging can
be performed.

PEPS-III
is loaded with the program to be tested from an IBM-compatible PC via
the printer port. As only the EPROM is being simulated, identifying
the type of CPU being loaded is not an issue for the PEPS-III. The
software supports systems with 8 Bit, 16 Bit as well as 32 Bit data
bus. Up two 4 PEPS-III units can be used on one PC printer port
|
Data
transmission is very fast. Up to 64000 bytes / sec can be transferred
into the PEPS-III. During data transmission and during testing the
PEPS-III remains linked to the PC. Data is not lost even after
switching off the system or disconnecting the cable. Power supply is
effected through the target system; amperage is only about a third of
that of the EPROM to be simulated.
PEPS-III
does have a reset output with a connector. This output will be held to
GND during data transmission. In simulation mode, the output is in
high impedance state and is tied on VCC with an internal resistor. The
software supports a debug mode outputting pulse chains via the reset
output to test the start-up behavior of the target system.
