1. Investigation of BANSMOM System m5151117 Yumiko Kimezawa February 3, 20121RPS

2. Outline Previous Work Current Work -Investigation of BANSMOM System -Requirement -Investigation of Stratix III Board Future Work February 3, 2012RPS2

3. Previous Work Implementation of 5-lead system Implementation of 10-lead system February 3, 2012RPS3 Logic utilization: 62% Not compiled

4. Investigation of BANSMOM System February 3, 2012RPS4 CPU memory -Until now Instructions and data are in the same space -Minor change Instructions and data are in different spaces Use of cache becomes efficient through separating these memories Instruction cache: Write back is not required Data cache: Write back is required Inefficient

5. Investigation of BANSMOM System February 3, 2012RPS5 Memory size (in 1-lead system’s case) -Master CPU instruction memory: 64Kbyte -Master CPU data memory: 32KByte -PPD CPU instruction memory: 32KByte -PPD CPU data memory: 32KByte -Shared memory: 2Kbyte Program size -Master module: 55 Kbyte (code + initialized data) -PPD module: 16 Kbyte (code + initialized data) Now, on-chip memory is used in the system CPU instruction and data memory make up a most portion of memory of the system

6. Requirement BANSMOM system needs a lot of cache memory February 3, 2012RPS6 Use of off-chip memory as not only shared memory but also cache memory will be required

7. Investigation of Stratix III Board DRAM -DDR3 SDRAM -DDR2 SDRAM -DDR SDRAM -QDRII + SRAM -QDRII SRAM -PLDRAM II February 3, 2012RPS7 Off-chip memory SRAM -QDR I/QDR II -NBT/Nobl I’m trying to investigate Memory capacity How to use off-chip memory Which memory to use

8. Future Work Optimization of BANSMOM system -investigate -Finish adding off-chip memory to our system February 3, 2012RPS8

9. Investigation of Stratix III Board Embedded memory -M9K memory block: 355 -M144K memory block: 16 -Embedded memory: 5,499 Kbit -MLAB: 1,775 Kbit February 3, 2012RPS9

10. Program Size 1-lead system -Master module  55 Kbyte (code + initialized data) -PPD module  16 Kbyte (code + initialized data) 2-lead system -Master module  56 Kbyte (code + initialized data) -PPD module  16 Kbyte (code + initialized data) -PPD module 2  16 Kbyte (code + initialized data) February 3, 2012RPS10
