Real-Time Operating System
HMEJPEG image compression
/decompression Library
Overview
Overview
Hyrtk is a optimized for embedded system
applications where a fast and deterministic
real-time response is required
The Embedded image Compression/Decompression Library for the HME’s GMS30C2216 provides high-performance JPEG image compression and decom-pression for still-image and multimedia applications.
Features
Features
Pre-emptive: Lower-priority tasks are preempted automatically by the highest-priority scheduled task
Fast task context switching (ca. 4~6 us)
Low latency time for interrupts without context switching (0.2~0.3 us)
Precise timing functions with a resolution of 1 us
Fast execution of kernel functions (2~3 us)
Fully integrated debugging of programs running in real time
User-defined subsampling for best image quality-compression tradeoff
User-defined resolution. Image resolution is limited only by available memory
Different compression ratios. User-defined quantization tables to achieve desired compression factor
