Bulldozer cache design

Each core has a 64KB Track Dozer  level data cache, 64KB instruction cache, 32-entry fully associative data cache page table (DATA TLB), complete out of order load / save unit, which can in each clock cycle Loading 128 within two or load a 128-bit instruction. Each module is equipped with 2MB 16 way associative secondary cache, 124-entry two page table cache can handle instructions and data requests. Bulldozer supports up to 23 secondary cache misses, memory system for maintaining consistency. Finally, all modules with a bulldozer processor core shared 8MB 64 way associative cache levels. Bulldozer significantly improves power management technology, support CC6 power state at the core level, at the module level can be supported by the secondary cache CC6 power gating (Power Gating). With power gating, idle core can be almost completely off, giving the other core leaving more space to accelerate. Full hydraulic crawler bulldozer has three modes of operation: acceleration frequency of the original preset reference frequency, acceleration frequencies all the core open, half of the core open. All core acceleration: If the excess thermal design power (TDP) space allows, bulldozers can be accelerated for all the core

Architecture Analysis

Embarking on designing the next generation x 86 processor cores, when, AMD's engineers considered necessary to achieve the core area of power consumption and optimization, and development of PC applications also allow engineers must find a new path, it is possible between different cores maximize peak bandwidth, and through sharing module to take advantage of every square millimeter of the core area. The end result is the ability to efficiently optimize the dual-core modular resources. Integer pipeline, a data caching frequently used features in each core has a separate functional units, prefetch, decode,drive bulldozers， floating-point pipeline, the secondary cache and other functional units in the two core in shared use. This design allows each core can use when you need a larger, higher-performance functional unit than each core has its own small independent functional units more economical core area. This design concept is a direct manifestation of the core area. Eight-core Bulldozer is AMD manufactured the history of the largest chip integrates approximately 1.2 billion transistors, but the application, the core area through the rational allocation of functional units,construction earthmover as well as the new 32nm SOI process is controlled only to 315 mm2, more than six-core, 45nm process Phenom II X6 9 percent smaller than the quad-core, 32nm HKMG technology Sandy Bridge only 46% larger

Information about high drive bulldozer

Front and rear guide wheel high driven bulldozers drive sprocket and walking system triangular arrangement, the drive sprocket set away from the high ground, to avoid the traditional bulldozer contact with the ground due to the drive sprocket suffered a direct impact load, so that the drive significantly improve the life of the system. mechanically driven bulldozer is doing the best global Caterpillar, currently the only Vision Engineering technology is mature and has formed a production. Vision Engineering since 1993 to develop and produce high drive bulldozer, 2003 batch to domestic and foreign markets, there are SD7 (230HP), SD8B (320HP), SD9 (430HP) 3 major product lines

Bulldozer was widely straight shovel

hydraulic track bulldozer uses a wide range of earth-moving machinery is the most commonly used operating machinery, occupies an important position in the earthwork construction. But because there is no wing blade, capacity is limited, in the process will cause earth leakage on both sides, it is not too long haul, otherwise it will reduce production efficiency. Typically small and medium haul bulldozer was 30 ~ 100 m, a large bulldozer haul generally not exceed 150m, bulldozer economic haul distance 50 ~ 80m.
When the transport conditions, earth-moving equipment was lifted lift cylinders, hanging in front of bulldozers; when the bulldozer into the working condition, the lower earth-moving equipment, the blade into the ground, can bulldozing forward, rewind can ground. When the bulldozer for tractor operations, the soil can push device removed.
Typically, hydraulic drive system bulldozers pushed forward dig earth, when the flat ground or piled loose material, widely it straight shovel; shovel or unilateral spoil hillside, often using oblique shovel; shovel cut on the slopes hard soil or digging ditches, using the side shovel.

The main purpose of bulldozers and construction

Mechanical Highlands dozers MYW in front of a crawler tractor or tractor tire mounting earth-moving equipment and operating mechanism of self-catering facilities machinery, mainly used for cutting excavation, backfill excavation, elimination of barriers, clearing the plot snow, land leveling, etc., can also be done short distance transport of bulk material shovel and stacking operations.
Bulldozer with ripper, can be turned loose Ⅲ, Ⅳ level above the hard soil, soft rock or rock chisel crack layer, scrapers and bulldozers to carry out excavation work, can also be used Highlands Bulldozer of direct push scraper blade scraper shovel to increase capacity (so-called shovel bulldozer aid), but also to assist the grader or a scraper to complete the construction work in order to improve the operating efficiency of these machines

History and the type of bulldozer

Bulldozer is a major mechanical earthmoving machinery, according to the walk is divided into two kinds of crawler and tires, because less tire bulldozer.
120KW of power greater than Crawler Earthmover, the vast majority use hydraulic - mechanical transmission. Such bulldozer from the introduction of Japan's Komatsu D155 type, D85 type, D65 type three basic bulldozer manufacturing technology. After localization, stereotyped as TY320 type, TY220 type, TY160 type Basic bulldozer. In order to meet user demand for the use of work conditions, our swamp hydraulic track dozermanufacturer on the basis of the above three basic bulldozer on, expanding product variety, the formation of three series of bulldozers. TY220 bulldozer products, including TSY220 Wetlands bulldozer, TMY220 type desert bulldozer, TYG220 type plateau bulldozer, TY220F Forest logging bulldozer, TSY220H model sanitation bulldozers and pipelayers DG45 type and so on. TY320 and TY160 type series bulldozer also expanding similar products. TY160 series there TSY160L ultra wetlands bulldozer and push TBY160 type Pa machines.

Bulldozer

Biggest bulldozer is an engineering vehicle with a large metal front dozer blade, dozer blade down when in use, and push forward chipping mud, sand and stones, dozer blade position and angle can be adjusted. Bulldozer digging can be done individually, earth and dump work, with flexible operation, convenient rotation required Face small, travel speed and other characteristics. It is mainly applied to three types of soil in a shallow dig short run, such as land clearing or leveling, Currently the world's small swamp bulldozer excavation depth of excavation and backfill little push small building height roadbed.
