Design and Implementation of High- performance

MAC Unit

Shishir Kumar Das, Aniruddha Kanhe, R.H. Talwekar

Abstract—In real-life, embedded devices like mobile phone, notebook computers are made use of RISC processor and DSP .In Digital Signal Processing (DSP) applications the critical operations usually involve many multiplications and/or accumulations. So, for real time signal processing, the high speed multiplier accumulator (MAC) unit is always a key element to achieve a high-performance digital signal processing. The goal of this project is to design and implement the MAC unit for high-speed DSP applications. For designing the MAC unit various multipliers and adders are required. The MAC unit is implemented using VHDL, synthesized and simulated using Xilinx ISE 12.1.

Keywords—: Adders, CAD tools, multipliers, VHDL.

N the majority of the Digital signal processing (DSP) ap- plications the critical operations usually involve many mul- tiplications and accumulations. So, for real time signal processing applications high throughput multiplier accumulator (MAC) is always a key element to achieve a high-performance digital signal processing. In the last few years, the main consid- eration of MAC design is to enhance its speed. This is because speed and throughput rate are always the concern of digital signal processing systems. Due to the increase of portable elec- tronic products, low power designs also become major consid- erations. This is because the limited battery energy of these portable products restricts the power consumption of the sys- tem.The main motive is to investigate various MAC architec- tures and the design techniques which are suitable for the im-
plementation of high throughput signal processing units.
The goal of this project is to design and implement Low power and high speed MAC unit. The total process is coded in VHDL. Finally, the whole process is implemented on Virtex 5
FPGA. The paper is organized as follows: Section 2 presents the overview of MAC unit. The implementation of MAC unit us- ing carry select Adder and Vedic Multiplier is discussed in Sec- tion 3. The implementation results are given in section 4, fol- lowed by conclusion in section 5.

A basic MAC unit consists of an adder, multiplier and an ac- cumulator. Usually, adders implemented are Carry-Select or Carry-Save adders, as speed is of utmost importance in DSP.

But if on chip area is to be considered then, Carry increment Adder can be used with an additional advantage of high speed [1]. One implementation of the multiplier could be Vedic Multi- plier [2].

2.1 Operation of MAC Unit

The inputs of MAC unit are fetched from memory cell and fed to the multiplier block of the MAC, which will perform multipli- cation and give the result to adder and then store the result in to a memory location. This entire process is to be achieved in a single clock cycle.
The proposed design consists of 32-bit floating point multiplier based on Vedic multiplication technique, 65-bit accumulator using carry select adder. To multiply the values of A and B, Floating point Vedic multiplier is used instead of conventional multiplier because Vedic multiplier can increase the speed of MAC unit. Carry select adder is used as an accumulator in this design. Apparently, together with the utilization of Vedic multi- plier approach, Carry select adder as the accumulator,
This MAC unit design is not only reducing the standby power consumption but also can enhance the MAC unit speed so as to gain better system performance.

The Fig.1 shows the block diagram of proposed MAC Unit consisting of 32 bit IEEE 754 based floating point Vedic Multi- plier unit.The result of multiplier is provided to the input of Ac- cumalotor through Carry select adder.

3.1 Multiplier Unit

In the proposed design of MAC Unit the Multiplier used is a 32
BIT IEEE 754 floating point multiplier based on Vedic multipli- cation technique. The multiplier for the floating point numbers represented in IEEE 754 format [3] can be divided in four sec- tions: Mantissa Calculation Unit, Exponent Calculation Unit, Sign Calculation Unit, and Control Unit [4].

Now the final result of multiplication of A and B is c4s4s3s2s1s0.

3.2 Adder Unit

Calculator App For Mac

Fig. 1. Block Diagram of Proposed MAC Unit
The Vedic Multiplication technique is chosen for the implemen- tation of this unit. This technique gives promising result in terms of speed and power [2,4].The Vedic multiplication sys- tem is based on 16 Vedic sutras or aphorisms, which de- scribes natural ways of solving a whole range of mathematical problems. Out of these 16 Vedic Sutras the Urdhva- triyakbhyam sutra is suitable for this purpose. In this method the partial products are generated simultaneously which itself reduces delay and makes this method fast. The method for multiplication of two, 3 BITs number is shown Fig.2.
Fig.2 Vedic multiplication Method
A carry-select adder is divided into sectors, each of which – except for the least-significant performs two additions in paral- lel, one assuming a carry-in of zero, the other a carry-in of one. A four bit carry select adder generally consists of two rip- ple carry adders and a multiplexer. The carry-select adder is simple but rather fast. Adding two n-bit numbers with a carry select adder is done with two adders (two ripple carry adders) in order to perform the calculation twice, one time with the as- sumption of the carry being zero and the other assuming one. After the two results are calculated, the correct sum, as well as the correct carry, is then selected with the multiplexer once the correctcarry is known.A carry-select adder speeds 40% to
90%faster than RCA by performing additions in parallel and reducing the maximum carry path.

We are evaluating the performance of the high speed low power MAC Unit implemented using, 32 bit IEEE 754 Floating point multiplier based on Vedic Multiplication technique. The Table.1 shows the simulation result of Vedic multiplier and also comparision between conventional Array Multiplier aswellas Booth Multiplier. These multipliers are implemented using VHDL In order to get the power and delay report the multipliers are synthesized using Xilinx ISE tool and Spartan 2E FPGA is used. Table 1 compares the simulation result of multipliers with Vedic Multiplier on basis of time delay and power.

Table1. Comparison between multipliers

Consider the numbers A and B where A = a2a1a0 and B =
b2b1b0. The LSB of A is multiplied with the LSB of B:
s0=a0b0;
Then a0 is multiplied with b1, and b0 is multiplied with a1
And the result added together as:
c1s1=a1b0+a0b1;
Here c1 is carry and s1 is sum. Next step is to add c1 with the multiplication results of a0 with b2, a1 with b1 and a2 with b0. c2s2=c1+a2b0+a1b1 + a0b2;
Next step is to add c3 with the multiplication results of a1 with b2 and a2 with b1.
c3s3=c2+a1b2+a2b1; Similarly the last step
The Floating point multiplier Unit of proposed MAC is designed in VHDL and simulated using Modelsim Simulator. The design was synthesized using Xilinx ISE 12.1 tool targeting the Xilinx Virtex 5 Xc5vlx30-3-ff324 FPGA. The paper shows the efficient use of Vedic multiplication method to multiply two floating point numbers. The lesser number of LUTs verifies that the hard- ware requirement is reduced, thereby reducing the power con- sumption. The power is reduced affectively still not compro- mising delay so much. The Table 2 shows simulation result of floating point multiplier [5].

New Features

Open API and gRPC Client Generation

Visual Studio for Mac now includes support for generating an API client from an OpenAPI or gRPC service. This includes the ability to generate the client from a local file or URL, manage service references, and regenerate the client code if the service changes.

To add add a new reference to an OpenAPI or gRPC service, right-click on the Connected Services node in the Solution pad and select Open Service Gallery.

After opening the Connected Services Gallery, you have the option to add either an OpenAPI or gRPC reference.

Clicking on either of the options launches a prompt which allows you to enter the service reference, either by file path or URL.

When generating a gRPC client, you can also select whether to generate the following client class types:

• Client
• Server
• Client and Server
• Messages Only (used to generate strongly typed classes based on message properties, with no generated server or client code)

When generating an OpenAPI client, you can specify the namespace and additional options which are passed through to the code generator.

Code generation is based on the dotnet-grpc and dotnet-openapi command-line tools.

After generating a service reference, you can view and modify it in the Connected Services Gallery as shown below.

For more information on using a generated OpenAPI client, see the Getting Started with NSwag tutorial.

For more information on using a generated gRPC client, see the Create a gRPC client and server in ASP.NET Core tutorial.

Right-Click to Run Unit Tests

When editing C# classes containing unit tests, developers can now right-click within the body of a test class or method to access options for running and debugging tests.

In addition to right-clicking in the editor, these new commands can be run using keboard shortcuts. If you're using the Visual Studio for Mac key bindings, the commands are as follows:

• Run Test(s): ⌘T
• Debug Tests(s): ⌘⌥T

See Default keyboard shortcuts in Visual Studio for Mac for more information on changing your keyboard shortcuts and The Visual Studio Blog for more in-depth information on this new unit test feature.

Visual Studio Tools for Unity
