LocalAlloc vs CreateFileMapping/ MapViewOfFile

Fri, 08 Jan 2010 13:21:28 UT

Test was run on iMx31 at 400 MHz.
Recently I went to an unexplained behavior with those functions.
Using LocalAlloc for (example) 32 MB takes about 450 ms and the same
allocation using CreateFileMapping/ MapViewOfFile takes about 3 ms.
Also filling buffer from LocalAlloc pointer is faster than filling buffer

implementing caching mechanism between RAMDISK & Nordisk

mudithasumanatu...@discussions.microsoft.com (Muditha Sumanatunga) — Fri, 08 Jan 2010 11:44:01 UT

I have created a 4MB RAM disk in my device. (this is a separate memory area
which is not in main memory) I have a NOR flash with 16 MB.
I want to create a Fast accessing (data writing) disk with Persistent
storage by combining RAM disk & NOR flash. The created disk size would become
16MB.

I have to map 4MB RAM disk to 16 MB NOR flash(to access the files). If I

It seems that part of the configuration needed to load the USB
mass-storage driver (USB host driver, mass-storage USB class entry,
storage manager profile) is inside the hive boot registry and part isn't.
If you need the USB mass-storage device to load the hives, move
everything inside the hive boot section, if you don't need it, move

File System Performance Tuning

I am currently working on WINCE6.0 file system performance tuning. In
theory, memory mapped file will increase frequently accessed file
data. I use 2 method to read through a file
Method 1

Check your registry to be sure that the entries related to USB storage (the
storage class driver, the host controller driver) are wrapped in ; HIVE BOOT
SECTION / ; END HIVE BOOT SECTION

Hi All,
When building windows CE 6.0 R3, i am facing a problem that USB storages
are not mounted. While debugging it found that When [HKLM\Init\BootVars]
Flags is set to 1, USB storages are mounted. But when Flags key set into 3,
USB storages are not mounted.
We used persistent storage to store hives. So it need to start storage

Re: linking a library(dll) to a project file in platform builder environment

I don't know the actual answer to this, but I would guess that a .dll
is generated in the same way that a static lib or .exe is generated.
I would guess that the compiler will have a bunch of intermediate
files that get generated from your various source files
(.asm, .c, .cpp, ...) and then get linked together at the last stage

A couple thoughts I'm having....
Code has to come from somewhere. From what I looked up after your
comment above, coredll.lib is basically a listing of symbols without
code so that linking can occur properly. But coredll.dll has to be
compiled from actual code, of which I'm assuming static library .lib

I think you need to re-read Bruce's response, it contains all the
proper information to fix your problem.
I wouldn't add coredll.lib to your bootloader as it will try to add it
as coredll.dll, think of it as an import library and not as a static
library.
It seems that you want coredll.dll because you want MmMapIoSpace,

Himanshu, Can you please stop changing the subject line when you
reply. This is making it very hard to follow the newsgroup thread when
you use an RSS feed, which is how many of the regular contributors
subscribe. Thanks, Andrew.
