Vítor Silva, Paulo Pinto, Paulo Cardoso, Jorge Cabral, Adriano Tavares
2021 Electronics  
system calls, which fully export these resources into the Linux OS user-space through a design-specific virtual file system.  ...  To address the integration of software threads and hardware accelerators into the Linux Operating System (OS) programming models, an accelerator architecture is proposed, based on micro-programmable hardware  ...  In addition, to implement composite operations, the Kernel Core uses the Scheduler services to select each system call from a concurrent implementation described by a user procedure.  ...

Comprehensive address generator for digital Signal Processing

Kini M. Ramesh, David S. Sumam
2009 2009 International Conference on Industrial and Information Systems (ICIIS)  
It is desirable to execute one loop of a kernel per clock.  ...  If implemented in a general purpose processor, address generation for signal processing applications will require execution of a series of instructions and use of datapath elements like adders, shifters  ...  A datapath suitable to execute a signal processing kernel is formed by writing microprogram. Microprograms for various kernels are stored in the microprogram memory.  ...

The Kernel cannot be regarded as an operating system — it does not even provide a logical facility for communication between the operator and either the system or user programs — but is rather a primitive  ...  The author became involved somewhat later as a design team member for the VME-B operating system [Keedy, 1976].  ... 

The MOLEN polymorphic processor

To prove the viability of the proposal, we experimented with the MPEG-2 encoder and decoder and a Xilinx Virtex II Pro FPGA. We have implemented three operations, SAD, DCT, and IDCT.  ...  To achieve the previously stated attributes, we present a new programming paradigm, a new instruction set architecture, a microcode-based microarchitecture, and a compiler methodology.  ...  ACKNOWLEDGMENTS This research is partially supported by PROGRESS, the embedded systems research program of the Dutch organization for Scientific Research NWO.  ...

Implementation of comprehensive address generator for digital signal processor

Ramesh M. Kini, Sumam S. David
2013 International journal of electronics (Print)  
Presence of a set of dedicated, efficient Address Generator Units (AGUs) helps in better utilisation of the datapath elements by using them only for kernel operations; and will certainly enhance the performance  ...  Pattern of data access in signal-processing applications is complex and it is desirable to execute the innermost loop of a kernel in a single-clock cycle.  ...  The reconfigurable AGU may have its own local microprogram or a finite state machine for generating sequences of addresses and may function under the supervisory control of a microprogram for that kernel  ...
