SEGGER veröffentlicht Arm Helium-Erweiterungen zur JPEG-Dekodierung für Renesas RA8D1-Mikrocontroller

(PresseBox) (Monheim am Rhein, )
SEGGER hat Verbesserungen für seine JPEG-Dekodier-Firmware veröffentlicht, speziell für die Optimierung der Berechnungen der inversen diskreten Cosinus-Transformation (IDCT). Diese Verbesserungen verwenden Arms Helium-Erweiterung, die in der neuen Renesas Cortex-M85MCU-Serie RA8D1 integriert ist.

Die neuen Firmware-Erweiterungen bringen eine Beschleunigung der zeitkritischen IDCT-Algorithmen, die für die Dekodierung von JPEG-Bildern erforderlich sind. Die Leistungssteigerung gegenüber MCUs ohne Helium-Erweiterung beträgt in der Regel das Dreifache. Bei voller Geschwindigkeit reduzieren die Erweiterungen die JPEG-Dekodierzeit auf dem Renesas RA8D1-Mikrocontroller von 12 ms auf 4 ms. In Kombination mit der Grafikbibliothek emWin von SEGGER wird so eine beeindruckende Dekodiergeschwindigkeit von 40 Bildern pro Sekunde (fps) für ein 837 m 207 YTEF-Hqta kuphjhfu.
