PICASO PROCESSOR 4D SYSTEMS PICASO Processor 6. 4DGL - Software Language 7. In Circuit Serial Programming ICSP The PICASO processor belongs to a family of processors powered by a highly optimised soft core virtual engine, EVE (Extensible Virtual Engine). The PICASO processor is a custom graphics processor. All functionality including the high level commands are built into the chip. This chip level configuration is available as a Firmware/PmmC (Personality-module-micro-Code) file.

PICASO PROCESSOR 4D SYSTEMS PICASO Processor 10. Memory Cards - FAT16 Format 11. Hardware Tools The PICASO Processor uses off the shelf standard SDHC/SD/micro-SD memory cards with up to 2GB capacity usable with FAT16 formatting. For any FAT file related operations, before the memory card can be used it must first be formatted with FAT16 option. The formatting of the card can be done on any PC system with a card reader.
