Rabbit VM

A hybrid VM: I need to do a lot of research.

What will determine if it is fundamentally a register machine or a stack machine is how function calls are made. For this, I think registers perform better.

Data Types

Int

start with just 64bit

eventually add int of any size int<64>

Float

same, start with 64bit

float<53,11> which is float<mantissa,exponent>

bool

Operator Categories

Flow

All the jump calls

Function calls

Thread

Start

Return (stop)

Pause

Resume

Sync

CAS

Swap

Add

Math

Security

An interesting application (related to dist.ribut.us) would be to classify secure operators. Access to filesystems, network, devices and so forth. Any application can run without elevated permissions with out any risk. Using a EigenTrust signing system, we can safely run scripts from untrusted sources.

To further elevate this, limits on memory, stack and total operation can be implemented.

Ops

set r v

<i,f>add r1 r2 r3

r1 = r2+r3

[or,and,xor,nor,nand] r1 r2 r3

r1 = r2 op r3

cp r1 r2

r1 = r2

swap r1 r2

load r1 r2

loads the memory value at r2 into r1

loadall

loads r2+ with the memory starting at r1

push r

push the register value at r onto the stack

pop r

pop the stack and write to r
