UPP
UPP (Universal Phone Processor) is the digital ASIC of the baseband.
UPP includes 8MBit internal RAM, ARM7 Thump 16/32–bit RISC MCU
core, LEAD3 16–bit DSP core, ROM for MCU boot code and all digital
control logic.
Main functions of the custom logic are:
1.
Interface between system logic and MCU/DSP (BodyIf)
2.
Clocking, timing, sleep and interrupt block (CTSI) for system
timing control
3.
MCU controlled general purpose USART, MBUS USART and
general purpose IOs (PUP).
4.
SIM card interface (SIMIf)
5.
GSM coder (Coder)
6.
GPRS support (GPRSCip)
7.
Interfaces for keyboard, LCD and UEM (UIF)
8.
Accessory interface for IrDA SIR, IrDA FIR and LPRF (AccIf)
9.
SW programmable RF interface (MFI)
10.
Programmable serial interface for Hagar RFIC (SCU)
11.
Test interface (TestIf)
Memory Block
For the MCU UPP includes ROM, 2 kbytes, that is used mainly for boot
code of MCU. To speed up the MCU operation small 64 byte cache is
also integrated as a part of the MCU memory interface. For program
memory 8Mbit (512 x 16bit) PDRAM is integrated. RAM block can also be
used as data memory and it is byte addressable. RAM is mainly for MCU
purposes but also DSP has also access to it if needed.
