Features

High-Performance, Compliant and Standalone Operation

Ultra high throughput in low-end silicon using scalable and transparent parallel processing

Full ITU T.81 compliance

4:4:4, 4:2:2, 4:2:0 and 4:0:0 (grayscale) image or video input

8-, 10- and 12-bit per component sample depth encoding

Single - multiple pixels - raster scan interleaved input and single, ready-to-use, JPEG byte stream output

Motion JPEG payload encoding

CPU-less, complete and standalone operation


Advanced Implementation

Up to 32 samples per clock cycle encoding

Algorithmic encoding latency of approximately 32 scan lines for 4:2:0 and 16 scan lines for all other sampling formats

CQP - VBR encoding mode with programmable Quality Factor (1 to 100)

Constant Bitrate (CBR) video encoding mode

Programmable output frame size

Programmable transmission buffer size

On-the-fly video bitrate changes supported

Configurable full on-chip or mixed on/off-chip memories implementation

Flexible optional off-chip memory interface

Independent of external memory type

Tolerant to latencies

Allows for shared memory access

Can optionally operate on independent clock domain

Avalon-ST and AXI4-Stream compliant streaming data I/O


Trouble-Free Technology Map and Implementation

Fully portable, self-contained RTL source code

Strictly positive edge triggered design

D-type only Flip-Flops

Safe CDC transfers when using more than one clock domain

No special timing constraints required

No false or multi-cycle paths within the same clock domain

No CDC transfers that need to be constrained
(all CDC paths can be excluded)
