The following applications (located in
${CHEOPS_BASE}/local/src/utils/) are miscellanious utilities for
managing an Cheops System.
This program is a part of the Cheops Ramlog system, used to log real time events in a fast and
compressed manner for later decoding and display. It is used to setup
and display the ramlog. Identical functionality is built into the
Magic7 monitor.
Usage:
where the optional dump and view params are:
Multiple -i or -e parameters (but not both) may be provided.
The <msg_set> is one of the following:
This program is used to reconfigure the instruction and data
caches on the P2 local processor, without crashing the currently
running operating system. It also allows the testing of the data
cache operation.
Usage:
This command displays a text string in an anti-aliased font on a
Cheops output module.
Usage:
This program prints out the current setting of the bus parameters
on the P2 local processor it is executed on. It takes no arguments.
This program is a looking glass into P2 memory. You can actually
watch how your buffers are allocated and filled !
Usage:
This program takes in an monochrome image sequence in datfile,
does motion estimation (ME), and outputs a datfile. A motion
estimation datfile should have 3 channels: x vectors, y vectors, and
minimum errors. There are other information which should be included
in the descriptor: frame distance, pel accracy, level of hierachical
motion estimation, ME mode (i.e. frame based, field based, dual prime)
and search range. Level 0 means ME is done by full search.
Usage:
Seems to be an MPEG version of modat.
Usage:
The ever popular NULL program, which does nothing, never returns, and
doesn't load down the CPU. It is useful for filling process slots while
testing. It takes no arguments !
This program seems to probe the output module, allowing interactive,
formatted printing of it's contents.
