• Establishing VelociTI Advanced VLIW as the architecture of choice for high- performance, low-cost DSP solutions. It is an alternative to better-known superscalar architectures. u StarCore claims it's a scalable architecture l First VLIW machine to target low-power apps u More execution units (13) than 'C62xx (8), but fewer instructions can be issued per cycle l Six for SC140 vs eight for 'C62xx StarCore SC140 MAC ALU BFU MAC ALU BFU MAC ALU BFU MAC ALU BFU BMU. The performance enhancements include: Our VLIW compiler has the following goals: 1. • A typical VLIW machine has; – instruction words hundreds of bits in length. Basic Computer Architecture CSCE 496/896: Embedded Systems Witawas Srisa-an Review of Computer Architecture Credit: Most of the slides are made by Prof. Wayne Wolf who is the author of the textbook. I made some modifications to the note for clarity. 8 Very-Long Instruction Word (VLIW) Computer Architecture ABSTRACT VLIW architectures are distinct from traditional RISC and CISC architectures implemented in current mass-market microprocessors.

Introduction to VLIW Architecture Paper Presentation: This Seminar Topic explains about Architectural plans of the VLIW which has a great trend of incremental performances in this generation. The VLIW style of architecture, as represented by Multiflow's and Cydrome's products [2, 3], addressed the issue of achieving high levels of ILP with reduced hardware complexity. These slides are partly from 18-447 Spring 2013, Computer Architecture, Lecture 20: GPUs, VLIW, DAE, Systolic Arrays However, these machines were specialized for numerical computing and had shortcomings with respect to scalar applications, i.e., • Reducing development time by half with new-generation tools designed for The VLIW Architecture: • Very Long Instruction Word (VLIW) architecture is generalized from two concepts; horizontal microcoding and superscalar processing. VLIW is an architecture designed to help software designers extract more parallelism from their software than would be possible using a traditional RISC design. – Common large register file shared by all functional units. VLIW is a lot simpler than superscalar designs, but has not so far been com-mercially successful. In addition to most of the standard optimizations, our compiler is built around a software-pipelining scheduler which is an enhanced version of a previously described algorithm.
