Edit NDS-in this paragraph-a comprehensive analysis of hardware performance.
High performance embedded processor
ARM946E-S and ARM7TDMI are made by Advanced? RISC？ Built-in machine development? 32? RISC？ CPU is widely used in automotive electronic equipment, mobile phones, hard disks, modems, industrial control, mass storage, network communication, wireless communication and various consumer entertainment electronic products. It has the advantages of low power consumption, high performance, small size and low price. Very suitable for handheld use. The ARM946E-S is the main CPU with the speed of 1-67MHz, which will be responsible for the main 3D and 2D operations. In order to make it run faster, Nintendo equipped it with a large cache instruction? Cache (instruction cache) 8k bytes. Data? Cache (data cache)? 4k bytes; TCM (tightly coupled memory): instruction? Cache (instruction cache) 32KBy? te，？ Data? A palm cache (data cache) 16kb? The machine is already very big. [Note: There are generally two ways to improve the processor speed: one is to increase the clock frequency; One is to increase the cache of the processor, and its speed is generally the same as the clock frequency of the processor or 1/2 speed]. ARM946E-S is a kernel with five-stage pipeline, which integrates Thumb extension function, debugging function and Harvard bus. Under the same process, it is more than twice the performance of ARM7TDMI. There is also an enhanced DSP instruction set. It can be used in applications that need control and DSP. Very suitable for NDS architecture [Note: Because NDS is 2D? Graphics? Engines and 3D? Graphics? Engines are of DSP type]; ARM7TDMI appears as an auxiliary CPU in NDS, mainly related to 2D? Graphics? Engine? 3D？ Graphics? The engine assists the ARM946E-S to run together, reaching the declared performance index and being compatible with GBA? Control input, output and other equipment. Equipped with off-chip 64K dedicated memory. It is a small, high-performance, low-power integrated 32-bit RISC processor core, originally developed for portable communication devices. The speed is 1-33 MHz. The ARM946E-S and ARM7TDMI are both produced by 0. 18um process, and * * * enjoys 32KByte? ( 16Kbyte？ X2) Off-chip dedicated memory. In this way, the ARM946E-S and ARM7TDMI can effectively perform performance close to R4000A (that is, the processor of N64 is not the same model as the R4000 of PSP, and the circuit architecture is completely different).
memory
In order to achieve the same picture effect as the N64 game, NDS integrates 4MB of main memory (the type is not said to be RDRAM). Compared with N64' s 4.5M, it is still a little worse, and the texture will definitely shrink compared with N64. But one problem that everyone ignores is the cache of CPU? The existence and function of dedicated memory (64k bytes) and * * * shared memory (32k bytes), and Nintendo also designed its 3D engine? As a frame buffer, 656KByte VRAM can fully accommodate N64 standard textures.
2D？ Graphics? engine
This time, in order to enhance the function of NDS, a 2D graphics engine is integrated to assist the processing power of two CPUs. But do you find that the 2D performance of NDS and GBA has not improved at all? What happened? Because 2D also needs to show a powerful picture [note: it is the background of 3D, the expression of 2D], which is why 2D should be integrated? This not only improves the fineness of 2D elements, but also does not affect the performance of 3D. Besides, are there more hair colors in the 2D image? The resolution is higher.
3D engine with N64 level function
When Nintendo announced that the function of NDS could surpass PS and rival N64, many players wondered whether ARM946E-S and ARM7TDMI were not as good as R4000A in number and frequency. Can NDS really do what Nintendo claims? The answer is yes. Because NDS integrates a 3D engine to help the CPU perform geometric operations. It can calculate 4 million vertices per second (this is the amount of calculation when all vertices are connected)? The multiple deformation of 120000 (in fact, it should be able to show more, because the vertices of large objects such as 3D background are connected together) and the filling rate of 30 million pixels make NDS reach the 3D function comparable to N64. On the basis of the special effects supported by N64, NDS has the effect of fog (making objects have the characteristics of fog. The principle of this special effect is to add white composition according to the distance to reduce the contrast between light and dark. It is different from the representation of real fog such as body fog. ) and cartoon rendering (adding outline on the edge of the material and making a few colors change gradually to produce cartoon effect or not using outline, only using color gradient to realize cartoon rendering such as wind stick).
The sound system beyond SFC is comparable to PS.
NDS has 16 PCM sound source, which is far more than SF*' s 8, so that **S can perfectly express the voice and sound effects close to CD quality, making it possible for music games to appear on NDS.
Convenient wireless connection
NDS is equipped with Wi-Fi wireless connection function, corresponding to IEEE802. 1 1 wireless network standard. Allows 16 players to enjoy a cassette within 10 meters.
Perfect operation button
In order to make up for the embarrassing situation that GBA operation buttons are not enough, NDS has been added? x？ Y key makes the game operation in NDS more diversified and perfect, more in line with the operating standards of future handheld games, and makes it possible for new types of games to appear on NDS.
Enhanced cassette medium
DS cassette adopts the storage technology of matrix semiconductor, which enables Nintendo to produce cassettes faster and cheaper. The cost of each cassette produced by a third-party manufacturer is about $ 6- 10, which greatly reduces the cost and price of cassette production by game manufacturers. Moreover, the capacity of the cassette is greatly increased to 1 gbit, which makes the game screen more beautiful and the growth of game time is not limited by the capacity. Another advantage is that the cassette can be equipped with a special DSP to enhance the picture effect of the game. Have you forgotten MD? Securities and futures commission era? With DSP, MD? SFC's 2D function upgrade can also realize 3D function, while NDS can upgrade its own function for PSP.

Edit this NDS- Palace masterpiece
NDS is not only the original Nintendo classic game series such as Pokemon, Mario, Animal Forest, Legend of Salda (Part II), Demon City (Part II: the cross of the pale moon, the portrait of the ruins, and the carved chapter taken away), but also the series of the brave fighting the dragon (4, 6, 9, monsters and monsters 2). ? Dragon Warrior series and Final Fantasy series have always been regarded as the two most successful role-playing games in Japanese game history, and the former has always tended to be sold on the most popular models. For several episodes of Dragon Warrior, it was decided to release them on NDS instead of the next generation console as expected, which undoubtedly convinced the outside world that NDS would dominate the game console market in the future. ? In addition, NDS has developed many interesting and classic new series of works, such as brain exercise series, soft-hearted gymnastics academy series, etc., which have aroused the popularity of puzzle and brain-strengthening games around the world. The new concept of music rhythm game rescue group series, surgical medical game super knife series, cooking practice game wonderful cook series, super popular pet game Nintendo series, adventure decryption game different color double memory and lost blue series also give full play to NDS functions.
