Introduction

The WinCE Utils utility package provides the ability for user-mode applications to access the CMEM utility libraries.

CMEM

The CMEM (Contiguous Memory) utility library provides the ability for user-mode applications to allocate and free blocks of physically contiguous memory. This is typically done to manage multimedia data buffers which will be worked on by multimedia algorithms, but the memory provided by this library can be used for any purpose.

The reason multimedia algorithms often require physically contiguous memory is that sometimes they're on another processor which may not contain an MMU (e.g. the C64P processor on a DM644x device), and/or WinCE-based algorithms utilize hardware accelerators (e.g. DMA, image co-processors, etc) which don't access memory through an MMU.

The CMEM module consists of the following packages:

The CMEM module supports the following devices:

Known Issues

None

See the Codec Engine Known Issues wiki article for issues found after these release notes were compiled.


Examples

WinCE Utils example apps and tests are provided in the ti/sdo/winceutils/*/apps directory.


Version Information

This product's version follows a version format, M.mm.pp.bb, where M is a single digit Major number, mm is 2 digit minor number, pp is a 2 digit patch number, and b is an unrestricted set of digits used as an incrementing build counter.

To support multiple side-by-side installations of the product, the product version is encoded in the top level directory, ex. winceutils_1_00_03_13.

Subsequent releases of patch upgrades will be identified by the patch number, ex. WinCE Utils 1.00.01.XX with directory winceutils_1_00_01_XX. Typically, these patches only include critical bug fixes.
