PROPOSAL FOR A NEW WORK ITEM

Date of presentation of proposal: 
1998-10-14	Proposer: 
JTC1/SC22	
Secretariat: 
ANSI	ISO/IEC JTC 1 N XXXX 	
		
A proposal for a new work item shall be submitted to the secretariat of the ISO/IEC joint technical committee concerned with a copy to the ISO Central Secretariat. 
Presentation of the proposal - to be completed by the proposer Guidelines for proposing and justifying a new work item are given in ISO Guide 26. 

Title: 
Information Technology - Programming Languages - Technical Report on C++ Performance (Technical Report Type 3)	
Scope:
This Technical Report will provide information regarding the performance of C++ code executing in environments with limited resources.  It will include a guide for users; a guide for implementers; programmer-directed optimization; and considerations such as low-level storage allocation, basic I/O hardware addressing and fixed-size date types.	
Purpose and justification:
It is proposed to establish a new project to produce a Technical Report with the specific contents here mentioned. The Technical Report is important as the use of C++ is growing very rapidly in performance-critical areas such as embedded systems, real-time systems, and financial applications.	
Programme of work: 
If the proposed new work item is approved, which of the following document(s) is (are) expected to be developed? 
____ a single International Standard more than one International Standard (expected number: ........ ) 
____ a multi-part International Standard consisting of .......... parts 
____ an amendment or amendments to the following International Standard(s) .................................... 
__X_ a technical report , type  3
