JPEG-Codec
We offer 2 IP-Cores for JPEG-Compression and Decompression:
JPEG-Compressor
- Performs JPEG-compression in 4:2:2 or 4:2:0 format from YUV 4:2:2-image (DCT, quantization, run-length-encoding, huffman-encoding)
- High speed (e.g. 150 MHz in ALTERA Cyclone IV, slowest speed-grade, which equals up to 150 (4:2:2) or 100 (4:2:0) Megapixels per second compression-speed)
- Very low resource-usage (e.g. ALTERA Cyclone IV):
- about 2250 LEs
- 5 M4K memory-blocks
- 8 18x18-multipliers
- VHDL-code included, vendor-independent
JPEG-Decompressor
- Performs JPEG-decompression of baseline JPEG-images (huffman-decoding, run-length-decoding, dequantization, IDCT, color-space-conversion)
- High speed (e.g. 150 MHz in ALTERA Cyclone IV, effective decompression-speed depends on image)
- Low resource-usage (e.g. ALTERA Cyclone IV):
- about 2850 LEs
- typ. 9 M4K memory-blocks
- 12 18x18 multipliers (including color-space-conversion)
- The decompressor is set up by a CPU depending on the contents of the JPEG-header-information, sample-source-code (in C) for ERIC5 is provided
- VHDL-code included, vendor-independent
Frequently Asked Questions
Is the license for just one project?
No. The license is for one development-location. I.e. the IP-core can be used by multiple developers for multiple projects as long as they are at the same physical location. Of course it is not allowed to give the VHDL-source to third parties.
Beside the license costs, are there per-unit royalties or other costs?
No.
Why are similar IP-cores from other vendors more expensive?
We do not know. We have based our pricing on what we think is fair (and what we would pay for such an IP-core ourselves). The price-difference is not because we think our products are of less value compared to competing products. Please note that we plan to offer also encrypted versions in the future with even further reduced prices, but at that point we might also increase the pricing of the non-encrypted versions.
