It was the basis for Intel and HP development of the Intel Itanium architecture, [3] and HP later asserted that "EPIC" was merely an old term for the Itanium architecture. [4] EPIC permits microprocessors to execute software instructions in parallel by using the compiler, rather than complex on-die circuitry, to control parallel instruction ...
Very long instruction word (VLIW) refers to instruction set architectures that are designed to exploit instruction-level parallelism (ILP). A VLIW processor allows programs to explicitly specify instructions to execute in parallel, whereas conventional central processing units (CPUs) mostly allow programs to specify instructions to execute in sequence only.

Transmeta Corporation was an American fabless semiconductor company based in Santa Clara, California.It developed low power x86 compatible microprocessors based on a VLIW core and a software layer called Code Morphing Software.
IA-64 (Intel Itanium architecture) is the instruction set architecture (ISA) of the discontinued Itanium family of 64-bit Intel microprocessors.The basic ISA specification originated at Hewlett-Packard (HP), and was subsequently implemented by Intel in collaboration with HP.
The parallelism is statically defined by the programmer. In this respect (and obviously due to the large instruction word width), the TTA architecture resembles the very long instruction word (VLIW) architecture. A TTA instruction word is composed of multiple slots, one slot per bus, and each slot determines the data transport that takes place ...
A MMU was also added so the ST231 can be used as a host processor. In digital video, STM 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 ...
