A user-space device driver can do many of the things that kernel drivers can t, such as perform a long-running computation, block while waiting for an event, or read files from the file system. Unlike kernel drivers, a user-space device driver can use other device drivers--that is, access the network, talk to a serial port, get interactive input from the user, pop up GUI windows, or read from disks. User-space drivers implemented using FUSD can be much easier to debug it is impossible for them to crash the machine, are easily traceable using tools such as gdb, and can be killed and restarted without rebooting even if they become corrupted. FUSD drivers don t have to be in C--Perl, Python, or any other language that knows how to read from and write to a file descriptor can work with FUSD. User-space drivers can be swapped out, whereas kernel drivers lock physical Memory.

Wishbone to LPC (Low-Pin Count) Bridge, includes master and slave modules. Supports 8-bit I/O Read and Write cycles, 8-bit Memory Read/Write cycles, DMA cycles, and up to 32-bit Firmware Memory read/write cycles. Serial IRQ support is also provided. None of this has been tested (yet) with a third-party LPC Peripheral or Host.

Run following Matlab commands to make sure the installation worked correctly. Unlike query function, filterdb does not load all waveforms to Memory but returns filtered database object. This is useful when the resulting set of the query is too big to fit in Memory. Consequent calls to read function can be made to read content of this filtered database object.

Functions are mappings from one Manifold to another. Discrete Functions are functions which can be represented using a finite number of values. Given the finite extent of computer Memory, algorithms which compute a function that satisfies some special properties are computing a discrete function which approximates a continuous function. Computing the function involves writing a set of equations that may be solved for the values representing the function.

This document specifies a collection of compiler directives, library routines, and environment variables that can be used to specify shared-Memory parallelism in C, C++ and Fortran programs. This functionality collectively defines the specification of the OpenMP Application Program Interface (OpenMP API). This specification provides a model for parallel programming that is portable across shared Memory architectures from different vendors. Compilers from numerous vendors support the OpenMP API. More information about OpenMP can be found at the following web site:

A programmable digital signal processor (PDSP) is a special-purpose microprocessor with specialized architecture and instruction set for implementing DSP algorithms. Typical architectural features include multiple Memory partitions (onchip, off-chip, data Memory, program Memory, etc.), multiple (generally pipelined) arithmetic and logic units (ALUs), nonuniform register sets, and extensive hardware numeric support [1,2]. Single-chip PDSPs have become increasingly popular for real-time DSP applications [3,4].
