Product Description
The A2e H.264 Encoder is still the industry’s smallest and fastest, which makes it ideal for FPGA designs with limited resources. A single core is capable of compressing 1080p30 video in a Spartan 6 device. The A2e H.264 Encoder supports H.264 variable and fixed bit-rate encoding of video streams. Multiple cores can be used for processing larger size or higher bandwidth images. We’ve added several enhancements to the latest revision of the core and supporting material.
