This paper presents a detailed architecture and instruction set of the SCAN cryptoprocessor. The SCAN cryptoprocessor is a modified SparcV8 processor architecture with a new instruction set to handle image compression, encryption, and information hiding based on the SCAN methodology. The modules for image compression, encryption, and information hiding are synthesized in reconfigurable logic an...
A previously proposed Reconfigurable Instruction Set Processor (RISP) architecture, which tightly couples a coarse-grain Reconfigurable Functional Unit (RFU) to a RISC processor, is considered. Two architectural enhancements, namely partial predicated execution and virtual opcode are presented. An automated development framework for the introduced architecture is proposed. In order to evaluate ...
This paper presents the architectural design of a reconfigurable and extensible Very Long Instruction Word (VLIW) processor. In addition to architectural extensibility, our processor also supports reconfigurable operations. Furthermore, we present an application development framework to optimally exploit the freedom of reconfigurable operations. Because our processor is based on the VEX ISA, we...
In this paper we present compiler extensions for the Molen programming paradigm, which is a sequential consistency paradigm for programming custom computing machines (CCM). The compiler supports instruction set extensions and register file extensions. Based on pragma annotations in the application code, it identifies the code fragments implemented on the reconfigurable hardware and automaticall...
To the present day, the performance of microprocessors has progressed dramatically. Recently, almost all computer systems use reduced instruction set computer (RISC) architectures. However, about 30 years ago, complex instruction set computer (CISC) architectures were widely used for almost all computer systems. The advantages and successes of RISC architectures are attributable to their simpli...
Closely coupling a reconfigurable fabric with a conventional processor has been shown to successfully improve the system performance. However, today’s superscalar processors are both complex and adept at extracting Instruction Level Parallelism (ILP), which introduces many complex issues to the design of a hybrid CPU-RFU system. This paper examines the design of a superscalar processor augmente...
Inefficient resources utilization is met in various embedded communication devices, which are based on standard processor cores and custom hardware modules. This paper addresses the inefficient resources utilization problem in MAC processor designs and presents a solution that is based on reconfigurable processor architecture and on dynamic-static instruction partitioning, depending on medium a...
A new architecture type that is recently evolving is the reconfigurable architecture which combines the benefits of ASIPs (Application Specific Instruction Set Processors) and FPGAs (Field Programmable Gate Arrays). Reconfigurable computing combines software flexibility with high performance hardware. FPGAs are generally employed to construct a reconfigurable block as it provides an instant tim...
In this paper, the architecture of an embedded processor extended with a tightly-coupled coarse-grain Reconfigurable Functional Unit (RFU) is proposed. The efficient integration of the RFU with the control unit and the datapath of the processor eliminate the communication overhead between them. To speed up execution, the RFU exploits Instruction Level Parallelism (ILP) and spatial computation. ...
