| | Explicitly Parallel Instruction Computing - Wikipedia, the free encyclopedia |
 | | Explicitly Parallel Instruction Computing ('EPIC) is a computing paradigm that began to be researched in the 1990s. | | | One goal is to move the complexity of dynamic scheduling of multiple instruction issue from the hardware implementation to the compiler, which can do the instruction scheduling statically (with help of trace feedback information). | | | They have been less successful in general purpose computing as it is debatable whether there is enough inherent instruction level parallelism in general purpose programs that these new features can exploit. |

| | VLIW: old architecture of the new generation |
| | EPIC was developed exactly to reach a higher degree of parallel instruction computing with an acceptable hardware complexity. | | | All such instructions can be divided into instructions of operation with a register stack, integer instructions, instructions of comparison and operation with predicates, memory access instructions, jump instructions, multimedia instructions, interregister move instructions, "miscellaneous" instructions (operations with lines and count of bits in a word) and floating-point instructions. | | | The first VLIW computer Cydrome Cydra-5 used a 256bit instruction and a special mode supporting a sequence of 6 40bit ops, that is why its compilers could generate a mixture of a parallel code and a serial one. |

| | From this perspective, the Explicitly Parallel Instruction Computing (EPIC) ISA is an interesting model for future machines as its primary design allows software to expose analysis information to the underlying processor for it to exploit parallelism. | | | Parallelism has been the primary architectural mechanism to increase computer system performance. | | | Experimental comparisons involving an Itanium-based EPIC model and an Intel x86-based CISC (Complex Instruction Set Computing) model indicate that the compiler and certain ISA details directly affect local and distant instruction-level parallelism. |

| | A 64-bit Instruction Set Architecture (ISA) Based on EPIC Technology |
| | Intel and Hewlett-Packard jointly defined a new architecture technology called EPIC (Explicitly Parallel Instruction Computing) named for the ability of the software to extract maximum parallelism (potential to do work in parallel) in the original code and "explicitly" describe it to the hardware. | | | Branches (instructions that change the flow of execution within the program) and memory latency (the time for data to arrive from memory) compound the already limited ability of today’s processors to achieve parallel execution. | | | The IA-64 implementation of EPIC technology enables new levels of parallelism and breaks the sequential execution paradigm (one instruction at a time) that exists with traditional architectures. |
