vmvecPop

 

 

Description

When evaluated, this vm instruction stores the top word from the internal Vector Processing Stack, into the destination, specified by the destination argument, and decrements the internal Vector Processing Stack by one position. The top stack word is stored, at the destination, as the data type specified by the type argument. There are no conversions made between different types. The initial values in the three pointer registers, the three increment registers, and the counter register are NOT altered by this instruction. This instruction may return an Error value. After the operation, the Instruction Pointer is promoted. The operation of this vm instruction is expressed in the following C expression:

The possible values of the type argument are any immediate integer value, indicating the data type, or any one of the following symbolic data types:

  • Float: [NumStack Only] (The top stack word is stored as a 32 bit IEEE floating point at the destination.)
  • Number: [NumStack Only](The top stack word is stored as a 64 bit IEEE floating point at the destination.)

    • The possible values of the destination argument are any immediate integer value, indicating the destination, or any one of the following symbolic data types:

    Virtual Machine Instructions

    AIS Lambdas are designed to be write-once-run-anywhere executable objects. This is accomplished via the virtual machine concept of software Lambda execution. Lambda virtual machines are designed to be mapped onto the actual host microchip at the server location, providing faithful Lambda execution wherever the Lambda may travel on the Internet. There are currently several virtual machines operating within Analytic Information Server. The DRM virtual machine uses a Dynamically typed Register Machine model to provide portable Lambda execution from high level dynamically typed instructions all the way to super fast microchip-level register execution. The DRM virtual machine runs in emulation mode during the testing and debug phases of Lambda development, and there is an AIS Lambda debugger available for Lambdas running on this virtual machine. During the final release phases of Lambda development, DRM virtual machine Lambdas are automatically converted to the NATIVE virtual machine on the host computer, using the just-in-time compiler. The NATIVE virtual machine is a faithful machine language translation of the execution rules in the DRM virtual machine onto the actual host microchip at the server location. NATIVE virtual machine execution runs at microchip-level execution speeds.
