IP for FPGA & ASIC Design

CAST, Inc. develops, markets, and supports reusable semiconductor IP (intellectual property).

Electronic system designers use these popular and standards-based IP cores and platforms instead of designing their own.

CAST offers A Better IP ExperienceHigh quality products, superior support, and 20 years of business success help us give designers a better IP experience. Search, browse, or request info above to find the CAST IP you need, or give us a call any time.

White Paper

Understanding—and Reducing—Latency in Video Compression Systems

CPU Subsystem Power Consumptioon Webinar by CAST, Inc.Video latency is the time between when a frame is captured and when it is displayed. Low latency is important for many systems where much delay or lag time would be unacceptable, from video conferencing to remote surgery. But the factors that determine overall latency in a system aren't always obvious.
