"Heads and Tails: A Variable-Length Instruction Format Supporting
Parallel Fetch and Decode"
    <http://www.cag.lcs.mit.edu/scale/papers/hat-cases2001.pdf>
    (PDF paper)

    To appear, International Conference on Compilers, Architecture,
    and Synthesis for Embedded Systems (CASES 2001),
    Atlanta, GA, November 2001. 

From the Abstract

The new head-and-tails (HAT) format splits each instruction into a
fixed-length head and a variable-length tail, and packs heads and tails
in separate sections within a larger fixed-length instruction bundle.

The paper evaluated 128-bit and 256-bit instruction bundles.

As an idle question, how hard would it be for cgen to support this?
