crossover, and duty-ratio adjustment and shift-equal functionality.7. Embedded dedicated Hard core　　embedded dedicated hard core is relative to the underlying embedded soft core, refers to the FPGA processing power of the hard core, equivalent to the ASIC circuit. To improve FPGA performance, chip manufacturers have integrated a number of dedicated hard cores inside the chip. For example: In order to improve the multiplication speed of FPGA, the main FPGA is integrated with special multipliers,

Source: http://www.union-rnd.com/xilinx-vs-altera-slices-vs-les/ObjectiveOften a friend asks me, "Am I using a FPGA or X-Home FPGA for this program?" Do they have enough capacity? How do they compare their capacity? "Of course, most of the time, when I design for the customer, I will use the highest capacity products directly, because our products are not sensitive to cost. However, this is still a comparison of the two products, simply write some of their own ideas for your reference, if there

Tribute to the originalHttp://blog.sina.com.cn/s/blog_6276db0e0101ary8.htmlTo compare Xilinx and Altera FPGAs, it is necessary to understand the structure of two giant FPGA, because of their respective interests, the two FPGA structure is different, the parameters are different, but can be unified to the LUT (look-up-table) lookup table.Take the example of Altera's Cyclone II series Ep2c35, as well as the xc3s500e of the Xilinx spartan-3e series.

You can define the role of the two-port pin after configuration, in just Devicepin option-->dual-purpose pins-->, can continue when the configuration is completed when the I/O port is used;(3). There are also a lot of hook options available under the General menu, which is generally not ch

The answer depends on what exactly you're trying to accelerate. GPU is really a "Software Acceleration" that can accelerate certain class of compute-intensive applications. the only interface to the GPU (NVIDIA or AMD) is PCI Express. FPGA, on the other hand, can be used for a broader range of accelerations. it has customizable iOS, so it can interface with any chip (with compatible signal levels, speed, number of IOS ). examples: TCP/IP checksum offload, ecryption/decryption, audio codec, appli

Xilinx's IO structure also has a pull-down resistor.I developed a project encountered such a problem: the transmitter, the power is required to output low level.

slow working mechanism for concurrent manageable work queues The reason for this is that "there has been a brief slow working mechanism in the kernel (slow work mechanism)" because in the mainline kernel, there have been slow working mechanisms (slow, work mechanism), but with concurrent management work queues (CMWQ) ,

Work queues are, on the surface, similar to taskets; They allow kernel code to request a function to be called at some time in the future. However, there are several notable differences between these 2, including: Tasklet the result of running in the context of software interrupts is that all Tasklet code must be atomic. Instead, work queue functions run in a particular kernel process context; As a result,
