چکیده

It is a challenge to convert the existing conventional DSPs' assembly code to that of VLIW DSPs'. We propose a new code migration method, which performs semantically equivalent code conversion. Key issues such as semantics of the conventional DSP code, specialized addressing modes and different data types are discussed.

A retargetable VLIW compiler framework for DSPs withinstruction-level parallelism

A standard design methodology for embedded processors today is the system-on-a-chip design with potentially multiple heterogeneous processing elements on a chip, such as a very long instruction word (VLIW) processor, digital signal processor (DSP), and field-programmable gate array. To be able to program these devices, we need compilers that are capable of generating efficient code for the diff...

Greedy and Heuristic-based Algorithms for Synthesis of Complex Instructions in Heterogeneous-Connectivity-based DSPs

VLIW DSP architectures can have heterogeneous connections between functional units and register files for speeding up special tasks. Such architectural characteristics can be effectively exploited through the use of complex instruction set extensions (ISEs). Although VLIWs are increasingly being used for DSP applications to achieve very high performance, such architectures are known to suffer f...

Machine-Description Driven Compilers for EPIC and VLIW Processors

In the past, due to the restricted gate count available on an inexpensive chip, embedded DSPs have had limited parallelism, few registers and irregular, incomplete interconnectivity. More recently, with increasing levels of integration, embedded VLIW processors have started to appear. Such processors typically have higher levels of instruction-level parallelism, more registers, and a relatively...

A VLIW-Based Post Compilation Framework for Multimedia Embedded DSPs with Hardware Specific Optimizations

In high performance and low power multimedia embedded system design, VLIW-based embedded DSPs compilers that exploit ILP have become popular and play an important role today. For this reason, we need optimizing embedded DSP compilers that can both generate capable and efficient code in terms of performance, power, size, and productivity. In this paper, we show a post-compilation framework that ...

A Study of Loop Unrolling for VLIW-based DSP Processors

With the growing popularity of DSPs and their associated applications, cost-effective software development has become a major issue. High-level language compilers are becoming more commonplace in the DSP world. While these compilers can generate correct code for DSP architectures, there remains considerable room for performance improvements. This paper addresses issues related to DSP compilatio...
