* Readout and Control Meeting @ KEK on 4 Oct.
I'll make a presentation titled "Direction on the Frontend Electronics".
* Development of CAM (Content Addressable Memory) LSI module for Trigger Logic
256K CAM LSI IC: KAWATETSU Address Processor KE5B256B1
Specifications: KAWASAKI STEEL LSI Div.
- Appearance of CAM LSI module: camboard.jpg
- Schematics (OrCAD Capture 7.01) - update 1999.12.10
CAM LSI MODULE: cam01.ps LS1: cam02.ps LS2: cam03.ps I/O 1: cam04.ps I/O 2: cam05.ps
// dsn file: Camlsi1.dsn
- PDF file from GND ( 1999.11.26
In the schematic CAMLSI_1.SCH, the assignment of connectors (CN1-6) must be fixed.
- Layout (V1) from GND ( 12.3
- Extended internal data bus to 16-bit one (cam01.ps, cam03.ps, cam04.ps Rev 1.5) and fixed so many bugs. ( 12.9
- Pull-downed data bus between KE5B256B1 and LVCC4245A (cam03.ps Rev 1.6). ( 12.10
- Decided to revise the layout to extend the data bus ( 12.14
- Schematic from GND ( 12.20
- Layout (V2) from GND ( 12.24
- CAM LSI Board arrived ( 2000.1.24
- SPARC CPU-5V (Solaris 2.5) booted. ( 2.2
- Created the module "vme" written by abel on Foundation 2.1i ( 4.13
- loaded the VME interface part into XC95108PC84 by Foundation 2.1i ( 5.31
- loaded the VME interface part into XC95108PQ160 ( 6.7
Internal logic: Schematic Part / ABEL Part
- Enable to read/write Control Register in CAM LSI by twice READ/WRITE 8-bit VME data cycle ( 9.14
One example of READ / WRITE Timing ( 9.18
- Configured with 1 entry by 1 segment ( 11.13
- Configured with 1 entry by 2 segments ( 11.20
- Got HHA (the Highest Hit Address) from CPU port by CPU port search ( 12.11
- Got HSTAT (the Hit Status) from Output port by OP Sequence & CPU port search ( 2001.2.1
- Got HHA from CPU port by IP Sequence ( 2.5
- Got HSTAT & HHA from Output port by IP Sequence ( 2.5
- Fixed the bug of Output port pin assignment ( 2.19
