The Fastcode Project

Memory Manager Challenge

The objective is to build the fastest replacement for the Delphi Memory Manager.

The following operating systems are supported:
Win95, Win98, WinME, WinNT, Win2000, WinXP, Win2003, Win64.


It is allowed to use any Fastcode function such as Move and FillChar.
Allocations must be at least 4 byte aligned.
All allocations must end at a 4 byte aligned address
The MM can use the 0-3 bytes at the end of blocks.
It is not allowed to use the patching principle for using any functions such as FastMove and FastFillChar.
There are two targets:
RTL Replacement. Same rules as for the standard RTL Replacement Target.
No CPU ID based selection of code is allowed.
Free blended: CPU ID based selection of code is allowed. All possible instructions are allowed. Must run on all processors from 486 and forward.
A valid entry for a given target gives 25 points.
Only one entry per target gives points.
A target winner gives 250 points
A target second place gives 150 points
A target third place gives 100 points
A target fourth place gives 50 points

Validation and Benchmark Tool:
Change Log: FastCode Memory Manager B&V 0.54 - 28-Oct-2005
