Agenda: %TOC% ---++ Action Item Review <strong>Meeting Discussion<br /></strong> * Cliff: Done [[GarbageCollection][Garbage Collection]] * Peter: Subtypes and Functions - add issues from previous meeting to proposals- in progress * Jim: Package based implementation of mod (record with modulus and integer value) - in progress * Martin: Integers and Logic Operators - in progress * Jim: Add warning to ?? on meta value * Trace back information from warning in package (such as numeric_std) to line number in entity that caused it. * Jim: Prepare ranking sheet * Integers: Arbitrary vs. Fixed Size? * A BigNum library type based on integer_vector (or other array type) cannot be used in for loops or indcies of arrays, where as a built in type potentially could. * Addressing a large RAM in a simulation. * What type of uses are BigNums used for: Are indexing and looping important? * How do you express a literal for a BigNum? As a string value or as an Universal Integer? * Python integer type is BigNum and uses regular integer values * Java has a BigNum package and uses string values or arrays of bytes * see: [[http://en.wikipedia.org/wiki/Arbitrary-precision_arithmetic][Wikipedia Arbitrary Precision Arithmetic]] *Topics for Future Meetings* * * Need more reviewers of matrix math package * Ryan: Arbitrary width real: see [[2012_MeetingNovember8][Nov 8 2012 meeting]] * Open - Multi dimensional Array restructuring: Array <--> Matrix Transformations [[2012_MeetingJuly19]] [[MeetingDecember15]] * Matlab has built-in reshape functions * In VHDL - explicit vs implicit defined operator * David Bishop: Requiring an implicit operator could delay implementations * Can this be handled by anonymous types on interfaces or generics on a package? * Language facility for creating implicit operators? * Ryan - Slicing Multidimensional Arrays (FT15) maybe related to above [[2012_MeetingMay24]] * Jim - Mark bugzillas for which we have a proposal with that status * Jim - Table driven modeling via protected types [[2012_MeetingMay10]] * Open - technical leader for 1076.6 activities? * std_logic_1164 uses 1076.6 attribute "RTL_SYNTHESIS_OFF" and "RTL_SYNTHESIS_ON" ---++ Ranking Criteria * Rank based on need * Item needs to be fixed * Useful for an application * Rank based on complexity * How hard to implement * Noted several items in Collected Requirements as Must Do * AI: Jim: Create ranking sheet. ---++ Review and Approve Meeting Minutes: * Motion: Martin 2nd:Cliff ---++ Next Meeting: Thursday [[2014_MeetingOctober2][October 2, 2014]] 8 am Pacific ---+++ Previous Meeting: Thursday [[2014_MeetingSeptember 11][September 11, 2014]]
