The efficient processing of MultiMedia Applications (MMAs) is currently one of the main bottlenecks in the media processing field. Many architectures have been proposed for processing MMAs such as VLIW, superscalar (general-purpose processor enhanced with a multimedia extension such as MMX), vector architectures, SIMD architectures, and reconfigurable computing devices. The question then arises...

Designers of embedded processors have typically optimized for low power consumption and low design complexity to minimize cost. Performance was a secondary consideration. Nowadays, many embedded systems (set-top boxes, game consoles, personal digital assistants, and cell phones) commonly perform computation-intensive media tasks such as video processing, speech transcoding, graphics, and high-b...

Clustered VLIW embedded processors have become widespread due to benefits of simple hardware and lowpower. However, the ILP inmost of the applications today is limited and discourages the design of wider issue processors. Simultaneous MultiThreading (SMT) is a well known technique to improve the resource utilization by exploiting thread level ILP. However, implementing SMT is not feasible for e...

We describe a VLIW architecture designed speci cally as a target for dynamic compilation of an existing instruction set architecture. This design approach o ers the simplicity and high performance of statically scheduled architectures, achieves compatibility with an established architecture, and makes use of dynamic adaptation. Thus, the original architecture is implemented using dynamic compil...

A key advantage of SIMD (Single Instruction stream, Multiple Data stream) architectures is that synchronization is effected statically at compile-time, hence the execution-time cost of synchronization between “processes” is essentially zero. VLIW (Very Long Instruction Word) machines are successful in large part because they preserve this property while providing more flexibility in terms of wh...

Clustered architecture processors are preferred for embedded systems because centralized register file architectures scale poorly in terms of clock rate, chip area, and power consumption. Although clustering helps by improving clock speed, reducing energy consumption of the logic, and making design simpler, it introduces extra overheads by way of inter-cluster communication. This communication ...

Clustered architecture processors are preferred for embedded systems because centralized register file architectures scale poorly in terms of clock rate, chip area, and power consumption. Scheduling for clustered architectures involves spatial concerns (where to schedule) as well as temporal concerns (when to schedule). Various clustered VLIW configurations, connectivity types, and inter-cluste...
