USB 3.0 software platform offers system portability solution
The TrueTask platform comprises a USB host stack, hub drivers, and the MCCI DataPump device stack -- all supporting both USB 3.0 and USB 2.0. Furthermore, the new platform supports dual-mode configurations that combine both USB 3.0 and USB 2.0 functionality in the same design.
MCCI's approach helps mitigate USB compatibility problems sometimes found with new devices. The TrueTask platform uses a series of APIs designed for portability. By writing application code to a higher level API, subsequent changes in lower layers required to support a new hardware design have little or no impact on upper layers. According to Terry Moore, MCCI CEO, the approach provides the flexibility needed to support a broad range of 32-bit MCUs with a modest impact on memory usage.
"You need a reasonably advanced MCU that supports pointers well, and [TrueTask requires] about 200 KB in a full configuration," said Moore. "But a stack for a reasonable embedded system [would require] about 64 KB RAM."
Priced starting at $50,000 for a single-project development platform, TrueTask is available for a variety of embedded platforms including Linux, MQX, Nucleus, micro-ITRON, Windows Embedded, Windows Compact Embedded, and non-OS/pre-boot environments. Local OS host stack emulations are available for Windows and Linux. The MCCI TrueTask USB is available now in limited distribution and will be generally available by the end of 2012.
