Title: Innovations of Hari Hampapuram

Introduction

Hari Hampapuram is an accomplished inventor based in Sunnyvale, California. He has made significant contributions to the field of processor technology, holding three patents that enhance the efficiency of computing systems. His work primarily focuses on improving instruction formats for very long instruction word (VLIW) processors.

Latest Patents

Hampapuram's latest patents include a compressed instruction format for use in a VLIW processor. This innovative software creates a compressed instruction format that allows for greater efficiency in the use of cache and memory. The instructions are byte-aligned and variable in length, with branch targets remaining uncompressed. The format bits specify how many issue slots are utilized in the following instruction, and NOPS are not stored in memory. Individual operations are compressed based on features such as whether they are resultless, guarded, short, zeroary, unary, or binary. Instructions are stored in compressed form in both memory and cache, and they are decompressed on the fly after being read from cache.

Another notable patent involves a compiler generating swizzled instructions that are usable in a simplified cache. This software produces a shuffled bit stream that allows for a simplified cache layout. The process includes code for receiving a compiled and linked object module produced by a compiler and/or linker, as well as code for swizzling the compiled and linked software to create a second object module. This second object module is designed to be deswizzled upon reading from a cache memory using a cache structure whose output bus wires are not crossed.
