For those who interested in discovering about main hardware components that operating on PSP motherboard, I have provided some further detail information regarding this issue.  I hope this info will help you to arise your knowledge about PlayStation Portable. 



Firstly, you should know about 3 main components that running on PSP motherboard and they are:

• Tachyon
• Baryon
• Pommel 

What are they?

They are important Motherboard IC's that working inside your PSP.

 
Further discription

BARYON

• The codename for the SYSCON microcontroller IC (refer to SYSCON for more information).

POMMEL

• The codename for the Power Control IC. A DC-DC converter controlled by SYSCON.

TACHYON

• The codename for the main CPU SoC IC. A Sony custom-made LSI which holds the main CPU (Allegrex), the VFPU coprocessor, the Media Engine CPU & its embedded DRAM, the Graphics Engine & its embedded DRAM, the AVC decoder, the Virtual Mobile Engine DSP, the KIRK & SPOCK crypto engines, and the 4KB embedded mask ROM which holds the PreIPL and routines to boot into service mode.

SYSCON

• The System Control microcontroller which handles everything from, controlling power to all devices (including the LCD, UMD drive, memstick, wlan, even the main cpu), keeping the date/time, sleep mode control, controls all external switches including all buttons & the analog nub as well as the headphone remote buttons/switches, LED control, main power & battery control, and even access to the PSP’s Service Mode (SYSCON is the chip responsible for detecting the 0xFFFFFFFF serial of the battery to enable service mode).

So, where does Sony placed these components on your PSP motherboard?

Since you already knew about these components,you also should know the CPU (Tachyon), Syscon (Baryon) and Pommel are different on different PSP mobos (motherboard). Sony keep releasing new motherboards and firmwares to stop the hackers exploiting PSP beside improving some systems in PSP. That why, the hackers found hard in releasing new Custom Firmwares.
