pe_arith
— DECmpp Sx processor element (PE) arithmetic operations test
Syntax
pe_arith [-bqt]
Description
The
pe_arith
command tests the operation of the arithmetic commands.
Using peek/poke, the front-end program loads four buffers of data into each PE’s
PMem: an 8-bit, 16-bit, 32-bit and 64-bit buffer.
The front-end program starts the back-end program and gives it the op code and
op size. The back-end program has each PE perform the requested operation,
each PE storing the result in another data buffer in its PMem. The back-end
program is halted and the front-end program directly checks the results in
PMem, using peek/poke.
Options
-b
Use this option to specify the Burn-in test; runs the diagnostic repetitively,
reporting the error count at the end of each pass.
-t
Use this option to specify terse message style; prints only the most essential
messages.
