2.6
Based on the cooperation between DSP Group (USA) and Siemens a Signal Processing
Core with Extensions (OAK) will be integrated in the DOC.
OAK Features:
• Up to 40 MHz / 40 MIPS
• 7 instruction groups with totally 72 instructions (including Bit Manipulation)
• Two independent 16-bit data busses (X and Y) each with demultiplexed address and
2.6.1
The DSP Kernel consists of four units: Computation Unit (CU), Bit Manipulation Unit
(BMU), Data Addressing Arithmetic Unit (DAAU) and Program Control Unit (PCU)
2.6.2
The integrated DSP (OAK) executes the following instructions:
• 20 Arithmetic and Logical Instructions: ADD, ADDL, ADDH, ADDV, SUB, SUBL,
• 12 Multiply Instructions: MPY, MPYSU, MAC, MACSU, MACUS, MACUU, MAA,
• 10 Bit Manipulation Instructions: SET, RST, CHNG, TST0, TST1, TSTB, CHFC, SHFI,
• 10 Move Instructions: MOV, MOVP, MOVD, MOVS, MOVSI, MOVR, PUSH, POP,
• 3 Loop Instructions: REP, BREP and BREAK.
• 10 Branch and Call Instructions: BR, BRR, CALL, CALLR, CALLA, RET, RETD, RETI,
• 7 Control and Miscellaneous Instructions: NOP, MODR, EINT, DINT, TRAP, LOAD
