ARM7 is an architecture, not a specific model. ARM7 processor can be made by any licensee of the technology to suit their needs. As such, their clock frequencies can range anywhere from 1 Mhz to 2.5 GHz.

Most likely you will need to patch it with DSLazy. You need to download it and replace the arm7/9.bin file with another one.
It depends what ARM you're talking about. The ARM7 uses the Van Neumann bus architecture (one bus for both data and instructions, and never both at the same time). The ARM9 uses a Harvard bus architecture (separate buses, one each for data and instructions).
I know of 3 different C interpreters that are interactive.(As opposed to many, many C compilers that are not interactive).They are:* PicoC : (currently) runs on x86, powerpc, arm, and blackfin processors, and is being ported to other processors.* Interactive C by Newton Research Labs apparently only runs on the 68HC11 (Handy Board)* Interactive C by KISS Institute for Practical Robotics apparently runs on the 68HC11 (Handy Board), the Hitachi H8/300 (Lego RCX), and the ARM7 (Xport Botball Controller).
There is still considerable controversy among experts about which architecture is better. Some say that RISC is cheaper and faster and therefor the architecture of the future.Others note that by making the hardware simpler, RISC puts a greater burden on the software. Software needs to become more complex. Software developers need to write more lines for the same tasks.Therefore they argue that RISC is not the architecture of the future, since conventional CISC chips are becoming faster and cheaper anyway.RISC has now existed more than 10 years and hasn't been able to kick CISC out of the market. If we forget about the embedded market and mainly look at the market for PC's, workstations and servers I guess a least 75% of the processors are based on the CISC architecture. Most of them the x86 standard (Intel, AMD, etc.), but even in the mainframe territory CISC is dominant via the IBM/390 chip. Looks like CISC is here to stay …Is RISC than really not better? The answer isn't quite that simple. RISC and CISC architectures are becoming more and more alike. Many of today's RISC chips support just as many instructions as yesterday's CISC chips. The PowerPC 601, for example, supports more instructions than the Pentium. Yet the 601 is considered a RISC chip, while the Pentium is definitely CISC. Further more today's CISC chips use many techniques formerly associated with RISC chips.So simply said: RISC and CISC are growing to each other.
