 Since many of these SoCs contain multiple ST200s (the STi7200 contains four ST231s), they actually shipped in excess of 70 million of these VLIW processors.The first ST210 compiler was the HP Lx compiler developed at HP Labs Cambridge, itself a descendant of the Multiflow Trace scheduling compiler and heavily modified by HP to target the embedded domain.Starting with the ST220, STMicroelectronics introduced compilers based on the Open64 technology.
