The realization of memory controller using the programmed gate array (FPGA) has the great advantage  â€“ it makes possible to reduce a quantity of elements in construction, which is critically importantly for systems, developed taking in account hard constraints on the overall sizes. Furthermore, and now and then this consideration leaves to the foreground, designers obtain the additional flexibility of  controller it can be added into the already existing project with the minimum modifications. Well-known developer and producer OF FPGA, Lattice semiconductor declared about the release of controller synchronous dynamic memory with the arbitrary access (SDRAM) TO DDR2, the supporting speeds exchange to 533 Mbit/s. Controller is accessible in the form core, ready to embodiment in the microcircuits FPGA of economical families latticeECP2 and LatticeECP2M, and also family latticeSC Of extreme, optimized on the criterion of speed. Controller is calculated for the standard the memory DDR2 SDRAM and allows the possibility of programming latency. As is known, the special feature of architecture  latticeECP2 and LatticeECP2M is the presence of the high performance parallel interface of input-output, which supports the transfer of signals LVDS with speed to 840 Mbit/s. Resting on this possibility, the core of controller DDR2 SDRAM it can fulfill its functions, being synchronized on the pulses of clock frequency to 266 MHz, which is equivalent to the speed transmission data of 533 Mbit/s. On the assertion of company, this record speed for inexpensive FPGA. It goes without saying, are supported the lower speeds: 400, 333, 266, 200 and 133 Mbit/s. Let us recall, during November of last year the company presented the realization of interface PCI express x1 and x4 for FPGA latticeSCM and LatticeECP2M. latticeECP2 LatticeECP2M	Add Comment ( 0 ) LATTICEECP2 LATTICEECP2M

The company quickLogic, which pays considerable attention to the development of element base with the lowered energy consumption, reported the about the release of the improved version of host- controller SDIO. Special feature of new product is the support of cards flash- memory of size secure digital high capacity (SDHC), which collects popularity both in the producers and in users. The secret of popularity is simple. As is known, the maximum volume of cards SD is equal to 2 Gb. At the same time, the cost of memory constantly lowered, and the need for the change disk with large volume  grows, especially in connection with a increase in the resolution of digital cameras and the propagation of the universal players, which ensure the survey of video. The introduction of format SDHC allow to overcome 2 Gb barrier (more precisely saying, to move aside it to the 32 Gb). The mentioned host- controller can be build it the microcircuits Of quickLogic families polarPro and Eclipse II, widely used in portable electronics. As examples of devices, for which was created the new product, producer calls the navigation systems, digital photo- and video camera. After enlarging the possibilities of host- controller, QuickLogic opens before the developers the simple way of adding the support SDHC to its projects. host- controller SDIO	Add Comment ( 0 ) HOST- CONTROLLER SDIO

New product is made on technical process CMOS, developed in Texas Of instruments, with the application of standards 130 nm. At the basis FRAM (energy-independent ferroelectric memory with the arbitrary access)  â€“ the improved architecture of cell, created by the specialists ramtron international, which occupies leading position in the region of developing the corresponding technologies. On the assertion of producer, the represented microcircuits have the density of  4 Mbit  maximum at the given moment. The product, which received designation FM22L16, get power from one source by voltage 2,7-3,6 v, has parallel interface and is release in the 44- contact case of type TSOP. Among the advantages of new product, specified on the special features of technology FRAM, the company calls high speed operation, practically unlimited number of cycles  reading and record, small energy consumption. According to arrangement and designation of conclusions new product compatible with microcircuits asynchronous static memory with arbitrary access (SRAM), therefore, first of all, it is oriented to application in constructions, where it adapts BY SRAM, in that number, in controllers, net equipment, devices for storing data, MFU, navigators. Logical organization FM22L 16- 256K x 16. Time of access is 55 ns, the duration of cycle is 110 ns. Record and reading is executed out with speed of system bus, without any delays. The declared number of cycles of rerecording  is not less than 100 trillions. The storage time of data in the absence of supply voltage is 10 years. On the operating speed and the energy consumption new memory exceeds memory of type SRAM. Thus, in the regimes of reading and record consumes 18 mA, in the regime of energy-economy 5h A. Are thus far accessible familiarizing models FM22L16. The limited deliveries are planned to the third quarter, and mass production must begin in the fourth quarter. Price of product is 19 dollars for the piece in the party made of 10000 pieces. FM22L16	Add Comment ( 0 ) FM22L16

In the presentation, released by microsoft in the conference GDC 2007 was discussed the following version of API directX 10.1. In this version will be added only one tenth in comparison with that released together with Vista DX10, and it means in the number of changes they will be only evolutionary. Revolutionary should be awaited in the new version API. To the number of update in DirectX 10.1 can be attributed the possibility to assign the independent regimes of blending for different render-target (render targets), the required requirement of support MSAA with a quantity of simple is not less than four, the appearance of control capability of arrangement of those selected sub-Sampilau from shader, a larger quantity of input and output registers in vertex shader, a increase in the accuracy of calculations, the filtration FP32 size, the massifs of cubic textures (cubemaps). In further plans Of microsoft - introduction into its firmware interface , system global lighting (Global illumination) both static- parametric, and dynamic, the hardware calculation of the laying out of rays (ray tracing) in real time, and also improvement in the textural management and sizes of compression, rendering of transparent ranges without the need for preliminary sorting and much more. This information will be joined well with earlier, report, that organized Intel visual computing group develops products, which ray of tracing will be on the forces in the real time. It is completely possible that after release of DX11 the three-dimensional card will make the jump, compared, perhaps, only with the idea 3dfx of its first hardware graphic accelerator voodoo.
