The MMIs are quite handy when you work with data that gets sent of to to either the VUs or the GS. The EE’s General Purpose Registers are 128-bit wide. What makes the EE different from other MIPS processors is that it has Multimedia Instructions ( MMI), these are specialized instructions that do 128-bit data operations.
The reason behind this is that the VUs only supports 32-bit floats and it would not be efficient performance-wise to do calculations with doubles, if you had to cast them to floats before sending them off to the VU’s, not to mention the lost precision. The EE FPU does not support 64-bit doubles, only 32-bit floats. You might already be familiar with MIPS processors from the Nintendo 64, PSOne or PSP. The EE Core is the R5900 processor, I will just use ‘EE’ to denote the MIPS R5900.Īs already explained, the EE is a MIPS R5900 processor clocked at around 294 MHz with 32 MB memory attached to it. The term Emotion Engine (EE) actually covers the main MIPS R5900 processor, the Vectors Units (VUs) and the Graphics Synthesizer.
PS2 BIOS DOWNLOAD NA MANUALS
Getting these manuals is a must, as you will find yourself looking for information contained in them again and again. I bought the PlayStation 2 Linux Kit just to get the manuals :-) The following manuals are included The EE, VUs and GS are fully documented in the manuals from Sony, these come with the PlayStation 2 Linux Kit. Lets have a closer look at the PS2 architecture. The core parts of PS2DEV are open source and produced by skilled people over long period of time, which means that PS2DEV is quite mature and almost anything can be created with the free information available.
PS2 BIOS DOWNLOAD NA SOFTWARE
The great thing about PS2DEV is that all the software you need to get started is free and most of it is open source. Just think of PS2DEV has a general term and not necessarily associated with.
PS2 BIOS DOWNLOAD NA PSP
regarding PS2 and lately also PSP and PS3. is just a gathering point for people to get help, discuss ideas, announce releases, etc. The term PS2DEV covers both home-brew hardware and software development and is often associated with the website, which hosts many PS2 software projects in its Subversion repository, and is the official home of the PS2SDK (PlayStation 2 Software Development Kit), which is one of the core parts of PS2DEV. This article is an introduction to home-brew PlayStation 2 Development also known as PS2DEV.
