Jim Peterson

3136-497: The performance and power efficiencies that FPGAs provide. OpenCL allows programmers to develop code in the C programming language . For further information, see high-level synthesis and C to HDL . Most FPGAs rely on an SRAM -based approach to be programmed. These FPGAs are in-system programmable and re-programmable, but require external boot devices. For example, flash memory or EEPROM devices may load contents into internal SRAM that controls routing and logic. The SRAM approach

3200-409: The point where some are now marketed as full systems on chips (SoCs). Particularly with the introduction of dedicated multipliers into FPGA architectures in the late 1990s, applications that had traditionally been the sole reserve of digital signal processors (DSPs) began to use FPGAs instead. The evolution of FPGAs has motivated an increase in the use of these devices, whose architecture allows

In 2014 Microsemi established a design group in Cork, Ireland, through the acquisition of Mingoa, which

3392-444: The registrar of Brigham Young University advised that they had double-checked and had no records of Peterson ever having obtained any degrees. An independent inquiry was made on behalf of the board by the law firm Munger, Tolles & Olson , which confirmed that in fact Peterson had not earned either degree. As a penalty for misrepresenting his academic credentials, Peterson paid Microsemi a fine and forwent his 2008 bonus. In 2012,

3456-407: The routing channels have the same width (number of signals). Multiple I/O pads may fit into the height of one row or the width of one column in the array. "An application circuit must be mapped into an FPGA with adequate resources. While the number of logic blocks and I/Os required is easily determined from the design, the number of routing channels needed may vary considerably even among designs with

3520-413: The same amount of logic. For example, a crossbar switch requires much more routing than a systolic array with the same gate count. Since unused routing channels increase the cost (and decrease the performance) of the FPGA without providing any benefit, FPGA manufacturers try to provide just enough channels so that most designs that will fit in terms of lookup tables (LUTs) and I/Os can be routed . This

3584-478: The serializers and deserializers in hard logic, depending on the FPGA. An alternate approach to using hard macro processors is to make use of soft processor IP cores that are implemented within the FPGA logic. Nios II , MicroBlaze and Mico32 are examples of popular softcore processors. Many modern FPGAs are programmed at run time , which has led to the idea of reconfigurable computing or reconfigurable systems – CPUs that reconfigure themselves to suit
