Checking eTPU_C generated code

| |

Byte Craft's eTPU customers generally use several different tools in their eTPU toolchain. The eTPU has a microcoded instruction set that may display the disassembly of the eTPU's instruction in several ways. The following example came from a conversation with a customer about instruction display formats of various tools that support the eTPU.

Byte Craft chose to display the instructions in the listing file as a functional representation of the instructions. In the following example an add with one side of the alu complimented and incremented is displayed as a subtract in our listings which is both functionally correct and a more compact representation.

This article describes a test we perform on our Code Development System compilers to test code generation. As a side benefit, it proves that C can match assembly, and beat it, even unexpectedly...
