Change Log for JOP3:
| February 23, 2003 |
Changing intern RAM to full synchron (except dout) for Cyclone port.
Should now be easy to port JOP to Xilinx. JOP runs now on Cyclone!
|
| December 6, 2002 |
Enhancements in extern memory access (wait instruction).
|
| November 8, 2002 |
TCPIP: Ethernet (cs8900) and slip interface work concurrent (Threads).
|
| October 29, 2002 |
Java: changes in tcpip code, TFTP to program flash (a lot faster than serial line :-)
|
| October 8, 2002 |
JopWriter: new method table (with virtual functions).
JVM: getfield, putfield, invokevirtual, invokespecial. new in com.jopdesign.sys.JVM.
|
| July 28, 2002 |
JVM: call com.jopdesign.sys.JVM.f_xxx() on unimplemented byte codes.
=> it's possible to implement 'complex' JVM instructions in Java!
JopWeb: display inputs of baseio and set outputs in the browser.
|
| July 26, 2002 |
JVM, JopWriter.java: system functions (io, mem) as special byte codes.
Some reorganization of Java files (packages).
|
| June 28, 2002 |
Java: Ethernet driver for CS8900A (for new board).
|
| March 24, 2002 |
VHDL: Java shift instructions are now JOP nativ instructions (single cycle).
Some enhancements in bc load from external memory.
|
| March 22, 2002 |
VHDL: doing imul in 'hardware'.
|
| March 16, 2002 |
VHDL/Java: Ethernet card with RTL8019AS attached to jop -> tiny Web server.
|
| February 25, 2002 |
VHDL: Sigma delta ADC (external components: two Rs and one C).
|
| January 31, 2002 |
Bug fix in JOPWriter.java.
Very simple web server (via slip).
|
| January 16, 2002 |
VHDL: simple fifo for uart.
JVM: imul, idiv, irem, ishr and a lot more Java samples.
|
| December 10, 2001 |
Jop instruction set changed from 16 to 8 bit!
JVM: automatic load byte code from external memory if program does not
fit in internal memory.
|
| December 7, 2001 |
VHDL: muxes befor jbc and rom removed.
Java goto and ifxxx decode in bcfetch.vhd => only one JOP instruction for all
Java branch types.
|
| December 6, 2001 |
Some clean up in the decode stage, prepare for instruction set change.
|
| December 4, 2001 |
JVM: bug in bc download corrected, more java examples.
VHDL: cp register removed (const pool is in external memory).
|
| December 3, 2001 |
JVM adapted for new 'class file' (memory map). Class structs and fields in external memory,
byte code still in internal. More than one (static) class works.
|
| December 1, 2001 |
JopSim: a simulator for JOP's JVM, written in Java :-)
New JOPWriter for jcc to generate memory map for more objects.
|
| November 15, 2001 |
Jump table for bc to JVM address mapping (but no new pipeline stage => slower max. clock).
New jp instruction instead of jp flag (not necessary with jump table).
JVM: getstatic, putstatic, newarray, arraylength, iastore, iaload, astore, aload.
|
| October 31, 2001 |
Download of Java programs via serial line ('boot').
|
| October 29, 2001 |
invokestatic, ireturn, return, indirect io addressing, special init bc.
|
| October 24, 2001 |
Jop assembler adapted, change in bz, bnz opcode (delayed address).
|
| July 31, 2001 |
Technology specific VHDL files for rams. No more .tdf files.
|
| July 15, 2001 |
Prime test program is running.
|
| June, 2001 |
Redesign of JOP2 => JOP3.
|
Change Log for JOP2:
| June 11, 2001 |
Enhancement for local variables in the JVM.
|
| June 10, 2001 |
Byte code operand fetch and branches in hardware.
|
| June 6, 2001 |
Prime test program for performance tests is running.
|
| June 4, 2001 |
Byte code fetch and decode in hardware, first JVM instructions ('Hallo World' and more).
|
| May 29, 2001 |
Memory interface to static RAM and FLASH.
|
| May 27, 2001 |
Assembler for JOP instructions.
Added Uart. Split core and memio (for simpler multi processor :-).
|
| May 26, 2001 |
Core: delayed branches (is this a good idea?).
|
| May 17, 2001 |
Two JOP2 fit in one ACEX EP1K30 and are running!
|
| May 16, 2001 |
First working version of JOP2 (blinking LED).
|
| April 16, 2001 |
First VHDL code (alu,...).
|
| April, 2001 |
Redesign of JOP => JOP2.
|
Change Log for JOP1:
| May 29, 2001 |
Error correction in JVM (sipush).
|
| May 26, 2001 |
Byte code caching for xxx_n instructions.
|
| January 27, 2001 |
Byte codes in external ram.
|
| February 14, 2001 |
Enhancing memory interface (write one cycle shorter).
|
| February 03, 2001 |
ECP interface added.
|
| January 27, 2001 |
Change memory interface to simulate 32 bit memory with a single SRAM.
Instruction ROM now for 1024 instruction. No internal RAM in 1K30 possible.
|
| January 14, 2001 |
First 'real' Java progam runs (prime).
|
| December 27, 2000 |
First working version of memory interface (SRAM and FLASH).
|
| December 3, 2000 |
JOP runs in real time with added serial interface (UART).
|
| October 4, 2000 |
First 'program' (3 instructions) runs on JOP (with debug interface on printer port).
|
| October 2, 2000 |
Creation of JOP (A lot is adapted from earlier processor designs between 1995 and 2000).
