reported in 2009 that it had shipped over 40 million systems-on-chip (SoCs) containing a VLIW processor from the ST200 family. 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. Compiling tools 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. In these compilers, the Open64 release has been improved by upgrading its GCC C and C++ front-end from 2.96 to 3.x and later 4.x, in order to achieve full C++ compliance. The GNU C extensions have been fully implemented in the Open64, including the asm statements. As a result, the Linux kernel can be compiled for the ST200. The other ST200 compilation tools are straightforward ports of GNU as, GNU ld, and GDB. References Digital signal processors Very long instruction word computing
