The SLED Specification Language for Encoding and Decoding, from the New Jersey Machine-Code
Toolkit, is one of Zephyr's Computer Systems Description Languages.
SLED takes the basic tree representation of instructions from the CSDL
core and adds attributes describing both assembly-language and binary
representations.
From a SLED specification, the Zephyr tools can generate an interface
that maps a machine-dependent Zephyr Intermediate Form either to assembly language or to
a binary image of the corresponding machine code.
Researchers can use this interface, e.g., to emit instructions
directly into a running process image, without losing the ability to
debug the more familiar assembly language.
