Executive Summary

Imagine is a stream processor that employs a two-level register hierarchy with 9.7 Kbytes of local register file capacity and 128 Kbytes of Stream Register File (SRF) capacity to capture producer consumer locality in stream applications. Parallelism is exploited using an array of 48 floating-point arithmetic units organized as eight SIMD clusters with a 6-wide VLIW per cluster. It achieves good performance in multimedia applications, signal processing, and scientific computing, but how it works in information security area remains unknown.
