Clock-gating is a well known technique to reduce dynamic power consumption of a hardware design. In any clock-gating based power reduction flow, automatic selection of appropriate registers and/or register banks is extremely time-consuming because power analysis is performed at the RTL or lower level. In a high-level synthesis (HLS) based design flow, to achieve faster design closure, one must be...
Hardware co-processors are used for accelerating specific compute-intensive tasks dedicated to video/audio codec, encryption/decryption, etc. Since many of these data-processing tasks already have efficient software algorithms, one could reuse those to synthesize the co-processor IPs. However, such software algorithms are usually sequential and written in C/C++. High-level Synthesis (HLS) helps in...
Managing power consumption in a System-On-Chip (SoC) design is becoming increasingly important. SoCs generally consist of various co-processors. Accurate power estimation of these co-processors at the highest possible abstraction level helps in performing early power-aware design tradeoffs. This paper presents a methodology to create abstract statistical power models for hardware co-processors and...
As adoption of system-level hardware design is increasing in industry and academia, accurate power estimation at this level is becoming important. In this paper, we present a system-level power estimation methodology, which is based on a high-level synthesis framework and supports sufficiently accurate power estimation of hardware designs at the system-level. For early and accurate power estimation,...
Accurate and efficient power estimation at higher-levels of abstraction is becoming increasingly important. However, tools and methodologies are lacking for such a task. In this paper, we present a methodology for accurate power estimation at high-level by reusing pre-existing verification or validation resources in the design flow. This novel methodology enables architectural exploration and design...
Embedded systems are becoming complex day by day and their increasing demand with shorter time-to-market is forcing designers to migrate to electronic system-level (ESL). One of the biggest issues with such battery-operated electronics is the power consumption. Facilitating power-aware architectural exploration at ESL requires a fast and accurate system-level power analysis capability. Existing frameworks...
