RISC (reduced instruction set) processor. One of two R4000 processors PSP CPU Core frequency of 333MHZ, its the digital cameras system bus 128BIT (Note: that is, with the memory or an external circuit connecting bus), through its Media Engine, 2, VME (Virtual Mobile Engine) and DMAC [ DMA is an Thorough analysis of PSP hardware knowledge.Therefore, the entire computer system efficiency greatly increased. It is the role of PSP through it so that CPU with the Optical Disc System, I / O devices PSP Headphone connected to read and handle the Optical Disc System, I / O devices (such as the handle, showing screen, U **, etc. interfaces are I / O device) of the Main Memory, Graphics Core1 information] to connect.

mini notebooks SONY for the PSP is equipped with two R4000 CPU cores. R4000 was developed by MIPS Technologies, Inc. integrated I-Cache (instruction cache specific capacity unknown), D-Cache (specific capacity of data cache unknown) and the FPU, VFPU (Vector Unit). One of the PSP CPU Core major source of 3D computing power VFPU both FPU and vector unit, the floating-point computing power has reached the 2.6GFlops (is in the 3D-CG Extended Instructions-3D instruction set to Wholesale PSP Accessories participate in the expansion numerical work), this is a P3 733 to achieve the volume of the High-performance CPU and embedded in the DRAM Surveillance Equipment
Spy Devices,
Spy Cameras,
Security Equipmentcore CPU acronym for Direct Memory Access. It is meant that the "direct access to memory." It refers to a high-speed data transfer operation, to allow the external device and to read and write data directly between memory, that is, not through the CPU, does not require CPU intervention. The PSP Accessories entire data transfer operation in the DMAC - Direct Memory Access Controller under control. In addition to the CPU data for the beginning and end of that deal, China PSP Accessories the CPU in the transmission process can be carried out other work. In this way, most of the time, CPU and input and output are in parallel operation
Because it is not integrated FPU VFPU (not rule out the possibility that I understand it correctly). It is also the frequency of 333MHZ, and the PSP CPU Core to share the because now the technology has not let GPU can simulate the effects of capacity, it can not take part in 3D computing, many sites that can collaborate with two Wholesale PSP Accessories CPU for 3D computing is wrong. front-side bus 128BIT, embedded a 2MB DRAM, DRAM bandwidth of 2.6GB/sec, it mainly as a media and China Cell Phone
Wholesale Mobile Phoneaudio decompression buffer memory. MPEG4 is the decompression to finish it.
even nVIDIA's GeForce series or ATI's RADEON series are inherent in its program to control the effects. The effects of the new, such as the new version to add a new DIRECTX effects must be replaced to support the version of the graphics DIRECTX, The game is not as China PSP Accessories PC graphics cards every 6-8 months as a replacement. GPU and the CPU floating-point operations than high, but there are limitations. Therefore, the choice of SONY is very wise - with a high floating-point operations to simulate the effects of the CPU.
PSP CPU Core is the role of the polygon used for pre-generation part of 3D computing and simulation effects, and its core integrated 30MB DRAM main memory such polygon can accommodate more data and high-resolution textures, the PSP Headphone main memory bandwidth 2.6GB/sec. PSP CPU Core to use its 128-bit bus and DRAM bandwidth connected, give full play to the PSP CPU Core ultra-high-performance (Note: Although the embedded memory test, it is still connected to the needs of the bus). The benefits of embedded memory is the CPU can directly access memory, reaction time to reduce the memory, and provide high-bandwidth. Also known as R4000 a Media Engine-media engine, as its name suggests PSP Accessories he is doing the voice of the media to deal with decompression and I / O management, rather than to do 3D operations. Therefore,
floating-point operations (this is the instruction set plus the SEE value is work 2.93GFLOPS (SSE)) Many people say that the GS to support the PS2 so little special effects, why game there are so many in fact do not support because of the effects of EE and FPU credit VUO + VU1 to floating-point psp's products website:http://www.epathchina.com,you can choose prefer psp accessories here operations EE total capacity reached 6.2 GFLOPS of floating-point capacity. VFPU of the PSP equivalent of EE on the VUO + VU1, So Do not Graphics Core does not support a lot of special effects, but you can rely on the FPU and VFPU to achieve the special effects do not support, many people said why did he not support Graphics Core,
