TJpgDec Tiny JPEG Decompressor

---

TJpgDec is a generic JPEG image decompressor module that highly optimized for small embedded systems. It works with very low memory consumption so that it can be incorporated into tiny microcontrollers, such as AVR, 8051, PIC, Z80, Cortex-M0 and etc.

Features

• Platform independent. Written in ANSI-C.
• Easy to use master mode operation.
• Fully re-entrant architecture.
• Very small memory footprint:
  • 3K bytes of RAM for work area. Independent of image dimensions.
  • 4.5-9.5K bytes of ROM for text and constants.
• Output format:
  • Scaling ratio: 1/1, 1/2, 1/4 or 1/8 selectable on decompression.
  • Pixel format: RGB888 or RGB565 pre-configurable.
