A number of people in various newsgroups have requested information concerning
the performance of the i860 and/or i860 compilers. A study just completed
at the University of Virginia examines in depth the processor-memory
interrelationship for a board consisting of an i860 and memory subsystem
constructed from page-mode DRAMs.
From an understanding of this interrelationship, guidelines are established
for implementing inner-loop operations in a manner consistent with the
processor architecture and memory system performance characteristics; by
adhering to these guidelines the assembly language programmer or compiler
writer can realize a 200-300% increase in performance over code generated
in a "straight-forward" fashion.
The implementation techniques presented throughout the report are dependent
on a memory system constructed with static-column or page-mode DRAMs. In
addition, the report focuses on vector operations (BLAS-like routines) and
scientific computations built on top of them.

login as 'anonymous'
2) cd pub/techreports/ipc
3) * set ftp to BINARY mode
4) get ipc_91-007.PS.Z
5) exit out of ftp
6) uncompress ipc_91-007.PS.Z
7) lpr ipc_91-007.PS
The report is formated for double-sided pages. Simply remove the
first 2 cover pages and drop the rest in a copier set for 1-sided
to 2-sided copy.
