We're pleased to announce the ASH WARE eTPU C Compiler Toolkit
(ETEC). Click here to download
a demonstration version.
The ETEC Toolkit is available for purchase either alone or packaged
with ASH WARE's eTPU Stand-Alone Simulator.
See our ordering pages
for details.
ETEC Toolkit
- C Cross-Compiler and Preprocessor
- Symbolic Macro Assembler
- Optimizer, Analyzer and Linker
Overview
- Compatibility Mode - Full support for existing legacy code, compile
your existing code base nearly "As Is."
- C compiler based upon the C99 (ISO/IEC 9899:1999) and draft "Embedded
C" (ISO/IEC TR18037) specifications.
- Supports eTPU and eTPU2 targets
- Windows command line toolset that can be integrated with IDEs such as Eclipse, PSPad,
Developer Studio, or others. ETEC also runs on Linux/UNIX platforms under
the WINE Windows emulator.
- Here at ASH WARE Inc, our philosophy is, The
worst bug is the bug you don't know about. Our public
website cross references all known bugs with all known releases.
Sign up for bug notification for all newly discovered bugs. Newly
discovered bugs are regression tested and fully
reported for all supported releases.
Supported Targets
- Full eTPU/eTPU2 support for Freescale's MPC55xx, MPC56xx Power Architecture micros, and MCF52xx ColdFire micros
- Full eTPU2 support for STMicroelectronics/Freescale SPC563Mxx Family - 32-bit
microcontrollers for automotive applications
Perennial Testing
The ETEC compiler tools suite V1.10A has now been extensively tested
using the industry-standard
Perennial CVSA test suite.
Perennial's licensing agreement prevents us from posting the results on our website
(which we would very much like to do)
but needless to say, these results are VERY, VERY GOOD indeed. All
newer releases are regression tested against Perennial to ensure continuous improvement.
Please call us to discuss.
Code Size and the Freescale eTPU Code Library
Freescale Set 1 through Set 4 are smaller (less code) when compiled
with ETEC. The ETEC compiled code works seamlessly with the existing host-side interface
and application code. These ports are available for download (as-is, without warranty).
Details and downloads can be found here.
New Features and Enhancements in Recent Versions
Detailed Features
- Command line interface runs under all Windows platforms.
- Runs on Linux/UNIX platforms under the WINE Windows emulator
- Fully compatible with ASH WARE Inc,'s eTPU/eTPU2 Simulator and Lauterbach's
eTPU Debugger.
- Several demos integrated with GNU Make highlight Freescale Set1,
a full engine demo, etc.
- Long Term Release Support - Ten year availability and support
for all releases that have active customers. [You maintain your
support contract and we'll support the release.]
- Generates highly optimized eTPU code that in many cases beats
existing solutions in terms of Worst Case Thread Length (WCTL,)
Latency (execution speed,) Code Density, Data RAM usage, and reduced
Data RAM access count (affects Latency.)
- Supports dual eTPU engine model. Only true global variables are
shared between engines; code does not conflict when running on both
engines. (This fixes an inherent bug in many users' code base, with
no code changes!)
- Generates no statically-known "dead code", helping meet
DO178B 100% code coverage requirements for avionic applications.
- Performance warnings when sub-optimal code is encountered (e.g. 8 or 16 bit variables in sub-optimal
locations, signed division, etc.).
- Supports both inline and stand-alone assembly of the existing assembly language
syntax.
- Auto-generates everything needed for host integration:
- Location information for all global and channel frame variables.
- Function number & entry table type information.
- Global and channel frame initialization data.
- Code array and calculated MISC.
- Numerous Report Files - such as .map, .lst. Our analysis file
provides detailed information on things such as maximum stack depth
and worst case thread length
- Performance Validation including validation of critical indices
such as WCTL validation.
- Built-in error handling library.
- Supports multiple data packing modes to allow users to compile
for reduced data memory (SDM) size, or for smaller & faster code
at the potential cost of greater SDM usage.
- Besides outputting in forms for actual inclusion in the target,
the code & debug information is output in standard ELF/DWARF2.0
format for use by the eTPU Simulator and other debugging tools.
- Includes a enhanced mode with a small amount of additional syntax
beyond C99 that provides a more intuitive and less failure prone
Windows event/response style mapping of software (eTPU functions,
threads, data) to the underlying eTPU hardware.

- The supported basic data types (signed and unsigned where appropriate) are:
- _Bool, char (unsigned int8), short (int16), int (int24), long int
(int32), long long int (synonymous with int32)
- fract8, short _Fract (fract16), _Fract (fract24)
- Embedded C Specification (TR18037) named registers are supported.
- Legacy Merging - Merge existing generated code as-is (.COD files)
with newly-written code using ASH WARE's eTPU Development Tool Suite.
Keep the old, move forward with the new.
- The ETEC library functions provide programmers with methods to
explicitly control atomicity, synchronization and coherency within
their code.
- Translation unit orthogonality with a "classic" two-stage
compile/link building process (though for compatibility purposes,
all code can still be included into a single translation unit)
- Fully supports the existing eTPU C programming model for channel
hardware access, condition code access, and entry table definition.
- Eclipse integration package including integrated build and one-click
error to editor (available soon on our website for download)
- Ash-Print - Instrument your code to provide user-defined and formatted
simulation trace files.
- Assembler supports existing customer's syntax both 'inline' and 'Stand-Alone'
